ETUP AND INSTALLATION

INSTALLING THE SOFTWARE

To properly install the Z8® Emulator GUI, first start the Windows application, then follow these steps:

1. Load the Z8 Emulator GUI diskette into compatible disk drive.

2. Select the Run command from the File menu, located under Windows Program Manager.

3. Type in the following at the prompt: “a:\setup” (or “b:\setup” if the diskette is in drive B:)

A dialog box will now prompt you for the directory into which the software will be installed (default is C:\Z8-ICE).

The setup program will copy the files into the target directory, creating a Z8-ICE icon in the Windows environment.

After the installation is finished, you can move the Z8-ICE icon into any program group of your choice.

Notes:

1. The installation procedure does not modify the “win.ini”, “autoexec.bat” or “config.sys” files.

2. An alternative way to install the Z8 Emulator GUI software is to copy all the files described in the following section to your target directory and manually create a program item by using the “New” command under the File menu of the Windows Program Manager. (Consult MS-Windows documentation if you need additional information about alternate install procedures.)

INSTALLING THE HARDWARE

Before installing the hardware, refer to Figure 2-1 for a rear view of the “generic” emulator and Figure 2-2, which provides a diagram for connecting the emulator to your PC and power supply.

Note: Proper functioning of the emulator assumes that the GUI software has been properly installed and runs correctly on your PC.

Quick Installation

This section provides you with a quick overview of the steps involved in setting up the hardware. The "Complete Hardware Installation" section, which immediately follows, provides a more detailed description of the hardware setup procedure.

1. Configure the emulator for internal ROM (if running in ROM Mode).

2. Connect to a +5V power supply and adjust to 0.6A (min.).

3. Connect the serial cable to the PC.

4. Connect the emulator to your design.

5. Set up the oscillator and option jumpers. (Refer to Table 2-1 and Figures 2-3 and 2-4.)

6. Connect the emulator to a logic analyzer (if using).

7. Power up the emulator. (Refer to "Powering Up" and "Powering Down" procedures.)

USER'S MANUAL

Complete Hardware Installation Configuring for Internal ROM. (You may skip this paragraph if you are using external

ROM.) This emulator is configured to run in "ROMless Mode," that is, it uses external ROM (Port 1 of the Z8 for multiplexed addresses and data). If, however, your application requires ROM Mode, follow these steps to reconfigure the emulator.

1. Remove the screws from bottom of the emulator and pull off the bottom of the case.

2. Straighten the handles of the programming sockets to an upright position. Note: We recommend that you leave the black front and back panels with the board.

3. Locate the socketed 20-pin IC labeled "U3" on the daughterboard. Note: For future reference, note the location of Pin 1.

4. Carefully remove the IC from the socket. Note: Use an IC puller or small, flat-bladed screwdriver, being careful not to bend the pins. Store in a safe place; the IC can be replaced on the daughterboard when using applications that involve ROMless Mode.

5. Locate the jumper header, which has eight jumper wires running diagonally across the top. Plug the header into the U3 socket so that Pin 1 is in the same corner formerly occupied by the IC Pin 1.

6. Carefully reassemble the emulator and replace the screws that hold the case together.

Connecting to a Power Supply. If your power supply allows voltage adjustment, do the following:

1. Turn the power supply on and adjust it to +5V.

2. Set it for at least 0.6A, if there’s a current-limiting adjustment.

3. Turn the supply off or make sure a nonadjustable supply is off.

4. Locate the power cable (red wire, black wire, and banana plugs on one end). Plug in

the black banana plug into the black jack on the power supply (labeled COM, GND, or with a ground symbol). Plug in the red plug into the red jack on the power supply (labeled "+" or "+V" or "+5V").

5. Plug the white connector on the other end of the cable into the matching 4-pin connector

on the back of the emulator. (This connection is "keyed" to ensure against an improper connection.)

Connecting the Serial Cable to the PC. Locate the serial cable and connect the male end to the female connector on the back of the emulator, then connect the female end to either the COM1, COM2, COM3, or COM4 connector of your PC.

Note: If connector availability is limited to a 9-pin COM1 through COM4, use a different cable or a 25- to 9-pin converter. (Zilog does not provide either of these items.)

USER'S MANUAL

INSTALLING THE HARDWARE (Continued)

Connecting to Your Design. (If your design is ready.) Locate the emulation cable for your

CCP™-based design.

Z8 Note: Wear a properly grounded wrist strap or similar ESD protection before proceeding

with this step. Plug one end of the emulator cable into your Z8 CCP socket, being very careful to orient

the Pin 1 marking (as indicated by the red mark on the ribbon cable) to match the way your board is built. Plug the other end of the cable into the matching blue connector on top of the emulator.

Note: The inductance and capacitance of the emulation cable may affect the signals to and from the emulator and target board, especially if the target board has low-current drivers, pull-ups, and pull-downs. We recommend that you drive the XTAL pins of the Z8 with the crystal oscillator on the emulator with the J2/J3 Jumpers removed.

USER'S MANUAL

Setting Up the Oscillator and Option Jumpers. The oscillator and option jumpers are

accessible on top of the emulator (see Figure 2-3). The clock for the emulated Z8 CCP can be provided from an oscillator in the emulator or from a TTL-level clock on your design. For electrical reasons, it cannot be provided from the oscillator on your design until you’re done using the emulator and have done one of three things: 1) programmed an EPROM or OTP Z8

and installed it in your design, 2) programmed an external EPROM and installed

it and a ROMless Z8 in your design, or 3) installed a masked-ROM Z8 in your design. Note: Each emulator is shipped with a standard oscillator, typically 12 MHz. If you want

another rate, remove the stock oscillator and install a different one.

The option jumpers, which are located on the top cover, allow you to configure things like whether the emulator provides power to your design on the V

pin(s) of the emulated Z8

CCP, and how the clock pin of the emulated Z8 CCP is connected (refer to Table 2-1).

WARNING

If your design already has a power supply, do not power from the emulator VCC pin. Powering Up. If anything unusual (such as unexpected sounds and smells) occurs the

first time you turn on the power supply, quickly turn off the power supply and check your connections. If your power supply allows voltage adjustment, adjust it again to +5V. (The value may be somewhat lower than +5V because of the load of the emulator.) If it has a current meter, ensure that the emulator is drawing within the rated current.

After power-up, depress the RESET button to reset the Z8 powering your design through the V

pin, turn on the power supply of the design.

Powering Down. When powering down, follow the procedure described below:

1. Depress the RESET button on the emulator.

2. Power-down the target application board (if using its own power supply).

3. Remove the target pod.

4. Power-down the emulator.

EMULATOR OPERATION

Resetting the Emulator. Pressing the RESET button on the emulator resets the state of

the target Z8 CCP and much of the status that you establish using the GUI. For example, it resets the emulated ROM size to 4 Kbytes, and clears all 32 Kbytes Breakpoint ROM. If your application board drives the /RESET pin of the Z8 CCP socket Low, the target Z8 CCP is reset. For example, it sets the Program Counter to %000C, but does not affect most of the other GUI and emulator status.

Note: After reset, you must wait a minimum of 5 seconds (for completion of self tests) before starting GUI.

WARNING

To run the emulator, you must always press the RESET button on the emulator before selecting the Z8-ICE icon.

ROM Size. The emulator has the selectable ROM size of 4K, 8K, 16K, and 32K. Breakpoint Implementation. The emulator bases its breakpoint facility completely on

addresses, rather than on inserting special “Trap” instructions into the program, which means you can set breakpoints in ROM on your target board. The emulator reads a 32Kx1 static RAM for each cycle emitted by the Z8 CCP during code execution.

EPROM/OTP Programming

The emulator provides OTP programming for the following devices: Z86E40, Z86E06*, Z86E30, Z86E04, Z86E3, Z86E03*, Z86E08, and Z86E07†. (Refer to Table 2-3: Emulator Programming Operations and Functions.)

* OTP device not currently available. † Use the E08 option to program the E07.

Notes:

1. Do not keep the OTP device in the ZIF socket while in Emulation Mode.

2. When programming a device, ensure that other programming sockets are empty.

Emulator Test Points

There are seven numbered test points on the back of the emulator; however, not all of the test points are used. The following table lists and describes the test points.

Table 2-4. Emulator Test Points

Number Description

1 Ground 2 Goes low during data strobe when the Z8 accesses a

MULATOR SAMPLE SESSION

Z8® EMULATOR SAMPLE SESSION

This sample session is designed to introduce you to the features of the Z8® graphical user interface (GUI) software and thoroughly acquaint you with the various GUI windows you will be using in this program. For best results, follow the steps in sequential order. Topic headings (such as “Using the Debug Window”) have been added to the Sample Session Procedure so you can better pinpoint specific topical “how to” information.

The chapter concludes with some brief notes and some figures that help explain the multiple window and multitasking capabilities of the GUI software. (Refer to Chapter 4: Summary of Menus, Commands, and Operations for more information about all elements of the GUI.)

Note: In order to properly demonstrate the program features, be prepared to import sample files (at procedural step 8) in this session. You can download Zilog sample files from Zilog's Bulletin Board Service (ZBBS). (Refer to Appendix A for the procedure to obtain these files.

Starting the Application

1. Press the RESET button on the emulator.

2. Double click the Z8-ICE icon. Confirm the COM port connections; change the default if necessary. The change is saved and will become the new default the next time around. If the communication attempt between PC and the emulator fails, you may have to check the connection or reset the emulator.

3. Wait for the initialization procedure to complete.

4. Click the OK button to continue (or the CANCEL button to quit), after the self-testing results are displayed.

Microcontroller Emulation

5. Select the Z8 microcontroller currently being emulated from the microcontroller section in the Configuration Dialog Box (see Figure 3-1).

RUNNING MULTIPLE INSTANCES

The Z8® emulator will allow several emulators running at the same time, if your PC has more than one communication port. Figure 3-3 shows two emulators running at the same time.

Figure 3-3. Running Multiple Instances

Note: Running multiple instances of the Z8 emulator GUI (two or more emulators running

simultaneously) requires more memory than single-emulation operation; therefore, we recommend using a PC with 8 Mbytes RAM. In addition, two more communication ports are needed when running multiple instances.

Each of these Main Menu items, along with all windows, subset menus, menu items, commands, and operations, are summarized in the following sections of this chapter.

CONFIGURATION DIALO G BOX

At start-up, the emulator GUI automatically detects which emulator is in use. (The user, however, can overwrite this by using a command-line option.) When a configuration dialog box is shown on the screen, you can choose the microcontroller and the ROM size you want to emulate. The code file you download to Code Memory is limited to the ROM size selected. Selected ports automatically reference port availability in the selected microcontroller. Other information about the microcontroller, such as the number of ports and extended register banks, can be observed but cannot be altered. Click the OK or CANCEL button to confirm or cancel the configuration.

Note: To modify the configuration, you must first close all open windows; the configuration command then reappears in the Main Menu.

FILE MENU

File-related commands are grouped under this menu. These commands are briefly described below.

Download To Z8 Code Memory: download a piece of Intel hexadecimal (hex) or binary

format code to Code Memory (Note that when downloading a hex file, the file size showing in the file downloading dialog box is the size of the memory the downloaded file will occupy, not the actual file size.)

ICEBOX File OTP Run Font Size Window Help

OTP

The CCP™ emulator provides OTP programming capabilities. Several operations can be performed:

Table 4-1. OTP Programming Operations and Functions

Operations Functions Performed

BLANK CHECK checks whether the OTP device is blank. VERIFY compares the contents of the Z8® Code Memory and the OTP

device. EXAMINE copies the contents of the OTP device to the Z8 Code Memory. PROGRAM writes the contents of the Z8 Code Memory to the OTP device. CHECKSUM calculates the Checksum of the OTP device only and

displays it on the screen.

Notes:

1. To obtain a Data I/O (such as UniSite, 3900, or 2900) calculated Checksum, the user

should first download the file with 00 padding option, then perform the OTP programming. This is because Data I/O fills its memory with 00 after power up.

2. Checksum differences may occur. During user-program download, the memory is

padded with code outside the user program memory if the user program is less than the emulation memory. The memory is padded with either 00, FF, or nothing according to user selection. This will not effect the user program; however, it will effect the calculation of the Checksum during the OTP programming because the Checksum is calculated through out the whole memory size of the OTP.

Selecting the Run menu displays four menu items (Trace Code, Trace Call, Animate, and Clear Trace), each of which, when selected, provides further program options. Each of the Run menu items are briefly explained below. (Refer to "Debug Window Elements" for further information about specific program commands and operations that appear as part of the Debug window.)

Trace Code

Selecting the Trace Code item provides a line-by-line trace capability while running the Debug program.

Trace Call

Selecting the Trace Call item provides a trace capability of the functions calls while running the Debug program.

Animate

The Animate item allows you to single-step through the various stages of execution. Note that the information is not displayed in real time.

Clear Trace

Selecting the Clear Trace menu item clears the content of the Trace field.

Debug Window Elements Code List

The content of the Z8 Code Memory is disassembled and displayed and any changes made to the memory are immediately reflected here. (Only line-down and page-down scrolling are allowed.) Use the JUMP button to go to an address outside the visible range. Clicking on a code line causes the address of that line to be inserted into the SET BRK, KILL BRK, and JUMP edit boxes.

Break Points

When you click on the SET BRK button, a break point is set at the address shown in the edit box. When you click on the KILL BRK button, the break point at the address shown in the edit box is deleted. The break point list box at the upper left corner of the window shows all the break points set. A click on the CLEAR ALL button deletes all the break points.

Jump/Reset

Click on the JUMP button to set the program counter to the address shown in the edit box. This is also a way to navigate the code listing.

USER'S MANUAL

Click on the RESET button to set the program counter to address 000c hex. A subsequent click of the GO button will cause the emulator to perform a RESET and then execute the Z8 code.

If you click the STEP button (instead of the GO button) the emulator will execute code, but

will not cause a device reset on the Z8 ICE chip. Trace Code/Animate

Animation is a mode where the code is continuously “single-stepped” through. A “GO” command will start the single steps and the current location of the PC will be displayed at each step. The trace option only works with Animation. You have the choice of tracing all instructions or tracing only the calls. The traced code is displayed in the Trace Buffer on the right of the window, which shows the last 100 traced entries.

Notes:

1. To execute code in real time, the Animation feature must be disabled. Trace or Animation options can be set from the “Run” menu.

2. Animation is not in real time.

Step/Step Over

Click on the STEP button to do single steps. The number of steps is determined by the number shown in the edit box (maximum of 99 steps). Never process the STEP command through the HALT or STOP instruction in your code, because the communication will be closed after processing the HALT or STOP command. “STEP OVER” only does one step at a time. It is the same as the STEP command except when the current instruction is a “CALL subroutine.” In that case, the subsequent code is executed in real time until the program returns from the subroutine. STEP OVER has the same effect as setting a break point at the instruction immediately following the current one, and executing the GO command.

Go/Halt

You can click on the GO button to start the execution of the Z8 program. If the Animation flag is off at this point, the execution is real time. Otherwise, it is simulated by single steps. After a “go,” the program stops when it hits a break point, a STOP or HALT instruction, or when you click on the HALT button. After a “go,” the user should not attempt any other operation except clicking on the HALT button to halt the execution.

Note:

If the application inadvertently goes into Stop Mode, the only way to halt the emulator execution is by doing a Stop-Mode Recovery (as defined by the user program). You may also reset the application using the TARGET RESET button.

Line Assembler

From the Code List field in the Debug window, you can change the Code Memory by entering the assembly code directly into the window line by line. After you input a line of assembly code, you can depress the Return key. The assembled code is then written to Code Memory.

Symbol Table

The window for the Symbol Table is located above the JUMP button. The Symbol Table can be loaded only under the following conditions:

1. A file has been downloaded into Code Memory.

2. The Debug window is selected; otherwise, the command is not accessible.

Once these requirements are satisfied, the Symbol Table command can be executed from the File menu.

For more information on symbol formats, refer to "Load Symbol", which is previously discussed in the "File" menu section of this chapter.

WINDOW REFRESHING

When you make a change in the Z8 Code Memory window, the code view in the Z8 Debug window will be updated automatically. When you run a program from the Z8 Debug window, the Z8 Status window will be updated automatically at each step, halt, or breakpoint. All the other windows (Z8 Register, Z8 Extended Register, Z8 Code Memory, Z8 Data Memory, DSP Memory) will not be updated automatically when the program runs. To refresh the window display to reflect the current hardware values, double click the caption bar of each window.

SAVING SESSIONS/RELOADING "SAVED" SESSIONS

You can save a session and reload a “saved” session. Selecting “Save session” saves the information about the position of the opened windows, downloaded Z8 code file, font size used, and debug flags such as “Trace” and “Animation”. Not all windows reappear upon reloading of a "Saved" session.

Note: On some DB9 connectors for the COM ports, the transmit/receive signal may be swapped and a "Null Modem" adapter may be required.

d. check if power supply can supply required current to the emulator. e. check if power supply is set at correct voltage. f. check if power supply is connected and turned on. g. after resetting emulator, you must wait 5 seconds (minimum) before running the GUI

TROUBLESHOOTING (Continued)

6. Clicking on the HALT button does not halt the emulator execution. If the application

inadvertently goes into STOP Mode, the only way to halt the emulator execution is by doing a Stop-Mode Recovery (as defined by the user program). You may also reset the application using the RESET button. (This will reset the emulator.)

7. CHECKSUM differences may occur because during download of the user program

the memory is padded with code outside the user program memory if the user program is less than the emulation memory. The memory is padded with either 00, FF, or nothing according to the selection by the user. This will not effect the user program. However, it will effect the calculation of the CHECKSUM during the OTP programming, because the CHECKSUM is calculated through out the whole memory size of the OTP.

8. Single-stepping into the Stop instruction will cause the ICE Chip to lock up, resulting

in register failure during the Self Test. The emulator must be powered down and powered back up again.

9. Halting the program execution or breakpointing when interrupts are enabled will

globally disable interrupts. The program must be reset and started from address 0000c hex.

10. Breakpointing in interrupt service routine and single-stepping pass the IRET state-

ment will cause global interrupts to be disabled.

11. Do not put breakpoint at address after Stop instruction. This will cause program

counter to continue at that location after a Stop-Mode Recovery.

12. Low-current pull-ups/pull-downs/drivers may see slower rise and fall times when the

emulation cable is used due to additional inductance and capacitance of the cable.
