Operating Modes

Data Generator Mode

The DTG5000 Series data timing generator is controlled by the DTG5000 software running on the Windows 2000 operating system and operates in Data Generator (DG) mode or Pulse Generator (PG) mode.

The DTG5000 Series operates as a data generator that outputs pattern data repeatedly. If you have defined a sequence, the The

DTG5000 Series either uses data created with the DTG’s built-in pattern editor

or imports data created with an external simulation software tool or other similar software, and then outputs the data. The output timing is determined by the sampling clock rate.

Pattern data can be controlled in the following ways:

DTG5000 Series runs it repeatedly.

Pulse Generator Mode

 Timing Control Delay, Width/Duty, Cross Point, Slew Rate

 Level Control: Amplitude, offset

The DTG5000 Series operates as a pulse generator. A typical clock pattern is generated as the data pattern being output. The output timing is determined by the output frequency.

Pattern data can be controlled in the following ways:

 Timing Control Pulse Width, Delay, Duty, Tr/Tf

 Level Control: Amplitude, offset

Data Structure

Internal Pattern Data

This section contains the following two sections, which provide information on the

DTG5000 Series Data Timing Generator data structure.

 Internal Pattern Data section explains the data timing generator objects such

as channel, group, block and sequence.

 Grouping and Channel Assignment section defines the groups and tells how to

use the Channel Group window.

This section explains the meanings of the data included in the windows. The data in the DTG5000 software consists of the channel, group, block, and sequence objects. This section details them in order.

Data Structure

Logical Channel

Physical Channel

The data timing generator has two types of channels: logical and physical. Logical channels represent one-bit width pattern data. The number of logical channels is 32 (4 channels x 8 slots) for DTG5078, or 8 (2 channels x 4 slots) for DTG5274 and DTG5334.

Logical channels themselves do not have the concept of length. The length of the pattern data on a logical channel is the block size defined in the Blocks window. Each piece of the pattern data has a value of 0 or 1. To create the pattern data, you can use the Data-Listing or Data-Waveform window.

One of the key features of the data timing generator is that each logical channel has its attribute value of the output setting parameters such as the output level, pulse width or delay time. You can set these parameters using the Level and/or Timing windows.

Physical channels are defined as the hardware channels of an output module installed in the data timing generator mainframe.

The number of physical channels available for the system is determined by the mainframe type and the types and number of output modules installed. Refer to Table 1-2.

The DTG5000 software has the output setup parameters, such as the output level or clock frequency, in its logical channels. To output actual data pattern outputs, do the following:

 Specify the physical channels to output the data within the logical channels.

 Send the output setup parameter to the physical channels to operate the

hardware properly.

To associate the logical channel with physical channel (this is also called channel assignment), use the Channel Group window. Refer to “Window Operation 4” in the User Manual 1.

Internal Pattern Data

Groups

Blocks

A group is defined as a set of logical channels. Grouping functions is especially useful depending on the DUT (Device Under Test). Several channels are sometimes used with the same output level and data format. In this case, handling multiple channels as one group is a useful method.

The number of logical channels that the system can accept is determined by the mainframe (32 for DTG5078, 8 for DTG5274, and 8 for DTG5334). In the Master-Slave operation mode, the number increases with the number of mainframes. The number of groups depends on how many groups the user divides into the logical channels. The total number of logical channels in each group cannot exceed the number of logical channels that the system can accept. By default, every logical channel is divided into an eight-channel group. To add a new group, you have to delete some groups or decrease the number of logical channels in a group to secure the logical channels required for the new group.

To create, delete, rename or resize a group, use the Channel Group window.

A block is defined as a set of groups that consist of logical channels. The block is an elementary data of signal output. To specify the block length, use the block size located in the Blocks window. The block size represents the pattern data length, or vector length. The block width is the sum of bit width in the group to which it belongs, that is, the total number of logical channels.

Sequence

By default, one block named Block1, whose size is 1000, is created.

Creating multiple blocks enables you to generate repetitive signal outputs by the blocks or sequential outputs with jumps. Even if two or more blocks exist in the system, only one method can be used for either grouping or channel assignment.

To create, rename, or resize a block, use the Blocks window.

Use the Data-Listing or Data-Waveform window to edit values (0 and 1) in the individual pattern data. Editing is possible by the block unit. To specify the block to be edited, you can use Select Block... from the Edit menu of the Data-Listing or Data-Waveform window, or use View Data-Listing or View Data-Waveform from the Edit menu of the Blocks window.

To set the voltage output setting parameter, use the Level window. To set the timing output setting parameter, use the Timing window. Both parameters can be set by the channel unit (except for clock frequency), but not by the block unit.

A sequence consists of blocks and subsequences. As the subsequence elements, one or more block names and the repetition of the blocks are defined. Using a sequence, you can output complex signals by defining blocks, number of times the subsequence repeats, and jump conditions.

Data Structure

By default, a sequence that continuously repeats Block1 is provided. To create a sequence or sub-sequence, use the sequence table in the Sequence window or Sub-sequence window.

Grouping and Channel Assignment

Grouping collects channels in a single group to enable setup, edit or display by group. To define a group or perform a channel assignment, use the Channel Group window. You can use the grouping function only in the Data Generator mode.

Grouping and Channel Assignment

Defining a Group

Assigning a Channel

A group is defined by the name and the channels included in the group. The defined group and channels are used for display by the channel or by the group in the Data-Listing, Data-Waveform, Timing, or Level window.

The channels to be defined are logical channels but not physical channels, which are actually installed to the hardware. The pattern data you created by pattern edit and the setting parameters such as the voltage and/or delay are attributes with logical channels.

To output a signal, you must assign the previously defined logical channels to physical channels. See Figure 1-3.

 Assign only one physical channel to one logical channel.

 Channel assignment can be performed, regardless of the bit sequence in the

group; any physical channels can be assigned to logical channels as desired.

 You can define the logical channels without being assigned to physical

channels.

 The physical channels that are not assigned to logical channels do not output

any signals.

Group List

The default group name(s) that appear in the Group List represent the maximum number of logical channels which can be used in the mainframe, and they are grouped by eight channels per group. The groups are independent of the installed output module(s).

Group Name. Assign a name to each group for identification. You can specify any 32-character or shorter string for a group. The name is case-sensitive, and the default is GroupXX.

Definable Number. Equal to or less than the number of physical channels supported by the mainframe. Up to 96.

Number of Channels. 1 to 96.

Predefined Grouping Options. The data timing generator provides three

user-selectable predefined options for grouping:

 8 channels per group

 1 channel per group

 All channels in one group
