INTRODUCTION

Realizer is an easy-to-use, Windows®-based environment that allows users with various levels of

programming expertise to design embedded applications for ST6 and ST7 microcontrollers using
graphical symbols that represent programming functions instead of coding application functions in
C or assembler programming language.

Realizer was developed by Actum Solutions and is available in several versions, including:

●

ST-Realizer II

●

Realizer Bronze

●

Realizer Silver

This document describes the differences between the ST-Realizer II and Realizer Silver versions.
Further, detailed information about ST-Realizer II can be found in the

1 Realizer feature comparison

The following sections list all the features that are available in the Realizer Silver version, which are

available

1.1 Multi Place

Components can be placed more than once in the schematic after selecting the symbol.

1.2 Multi Connect

When connecting the input and output symbols to device pins, you can select the I/O in a combo
box. This allows you to connect all I/Os without double clicking on each I/O symbol.

1.3 Store String

Text strings entered in a text box will be stored and used when a new label is placed, so that you
don’t have to type the string a second time.

1.4 Scroll Wire

When you connect symbols to each other, the screen scrolls automatically as the mouse pointer
exits the screen (auto-pan).

1.5 No Borders

In Realizer Silver, this feature allows you to draw schematics that go outside the page borders. In
ST-Realizer II, schematics are limited to the page.

1.6 Status Box

Realizer Silver provides more information when analyzing projects. ST7-Realizer II reports I/Os,
variables by type and required memory space.

1.7 Actum Menu

Some functions have been added to the menu to make the Realizer Silver user interface more
intuitive, such as:

● F5 — refresh screen,

● CTRL +drag — to move components horizontally or vertically,

● Arrow keys — to move components using the keyboard. Use the CTRL button to increase the

steps when moving.

1.8 Realizer Help

The

Realizer User Guide

is provided with the installation of Realizer Silver.

1.9 Global Labels

Labels can be applied to the entire design. With ST-Realizer II, labels are only applied to the sheet
upon which they were placed.

1.10 Controlled

This feature allows you to control the execution of the different sub-schematics. If sub-schematics
are not executed, the loop time is reduced.

1.11 Symbol Code Support

This allows you to create a symbol and write the assembly code for it. The assembly code is stored
in the symbol itself instead of in an include file. In ST-Realizer II, it is necessary to edit the symbol
code in the include file.

1.12 Active Low Outputs

Outputs can be initialized high at startup. The outputs of ST-Realizer II are set high in the first loop,
whereas Realizer Silver allows you to choose to set the outputs low or high at startup.

1.13 LCD Control

Realizer Silver allows you to use the LCD peripheral on the ST6240 and ST6280.
