ACTUM REALIZER
FOR THE ST62 & ST7
SOFTWARE AIDED COMPUTER ENGINEERING TOOL
FOR ST62 AND ST7 8-BIT MICROCONTROLLERS
GRAPHIC DESIGN AND DEBUG
The ST-Realizer allows you to use the same tool
for ST62 and ST7 microcontroller families. With a
single click, using the powerful graphics editor and
compiler, you can generate complete software ap-
plications for the ST62 and ST7.
Migrating from one ST62 or ST7 family device to
another is done simply by clicking on the name of
the microcontroller.

ACTUM REALIZER
FOR THE ST62 & ST7
DESCRIPTION
The ST-Realizer is a version of The Realizer by
Actum Solutions (1), The Netherlands, dedicated
to the design and development of applications for
the ST62 and ST7 family of microcontrollers
(MCUs).
The schematic-based architecture for both design
and Simulation allows engineers, without learning
the MCU architecture, to create a microcontroller
application, with all the benefits and flexibility that
the microcontrollers provide.
DESIGN
Use your knowledge of the application to decide
Input/Output functions, then draw and build up the
application functionality graphically using the in-
dustry standard symbols from the library (or create
your own). A state machine can be added if re-
quired. Draw wires between the symbols on-
screen to create the application. The schematic
can be printed for documentation.
ANALYSE
Select an ST62 or ST7 device and allocate I/O
functions to actual physical I/O pins. Run the Ana-
lyzer to verify and run process analysis on the ap-
plication as drawn. If errors are found, edit the
schematic and re-analyze. When all is satisfacto-
ry, allow the Analyzer to generate the efficient
ST62 or ST7 software code.
DEBUG
Use the integrated ST62 and ST7 Symbolic Sche-
matic Simulator to stimulate and monitor the circuit
functionality directly on the schematic. Add Virtual
development tools to the circuit as graphical sym-
bols and run or step through the functionality to
verify that the application works asexpected.If not,
return to the Schematic entry environment and re-
vise the drawing, then Analyse and Debug again
until the function is as desired.
Now you can easily program EPROM or OTPST62
or OTP ST7 microcontrollers with the final gener-
ated software to build prototypes. Field trials can
then be performed with confidence that the appli-
cation program functionality has been assured,
giving less time needed for expensive field modifi-
cations.
EXPANSION
The Realizer can produce a complete standalone
application program, or just the main part to start-
up and control the program functions designed on-
screen. In this latter case, the code can be linked
with other library routines to expand on the func-
tionality. The expanded code is then able to be de-
bugged with the ST62 or ST7 Hardware Emulation
Tools.
