4.5.4 Simulation
The Polychrony services provides several kinds of generators which needs external tools
to be used or executed: SynDEx tools for sdx files, Sigali (distributed with the classical
Polychrony distribution) for z3z files... The C, C++ or Java code generation is dedicated to
simulations.
By default, the code (C, C++, or Java) generated by Polychrony will read input values from
a files called R<input name>.dat (or RC_<input name>.dat if the input signal is of type
event) and will write output values into a file called W<output name>.dat. These input files
has to be created and filled by the user (one value per line, and for event signal, 0 for
absence and 1 for presence).
4.5.4.1 C/C++
For C and C++, you will need to use an external C/C++ compiler. The Polychrony libraries
are provided and can be found in the Eclipse plugins directory and specifically in:
●fr.irisa.espresso.ssme.polychrony.win32.win32.x86/lib
for Windows x86
●fr.irisa.espresso.ssme.polychrony.win32.win32.x86_64/lib
●fr.irisa.espresso.ssme.polychrony.gtk.linux.x86/lib
for Windows x86_64
for Linux x86
●fr.irisa.espresso.ssme.polychrony.gtk.linux.x86_64/lib
for Linux x86_64
●fr.irisa.espresso.ssme.polychrony.cocoa.macosx.x86/lib
for MacOS X/Intel x86
●fr.irisa.espresso.ssme.polychrony.cocoa.macosx.x86_64/lib
for MacOS X/Intel
x86_64
Currently, there is not automatic generation of makefile to compile C/C++ file.
4.5.4.2 Java
For the Java generation code, we take benefit of Eclipse which is originally a Java
environment which provides several facilities to manage Java project. The call of the Java
generation code creates (if all previous operations are executed without errors) a Java
project containing the Polychrony Java libraries (SignalJavaStd.jar, and
SignalGraphicalJavaStd.jar) and the Java source classes are generated in the src
directory of the project. There may be some errors in the Java code if your SSME model
has constant parameters. The correction of these errors consists in replacing the
UNDEF() calls by the value of the constant parameter.
To execute the simulation, you have only to right-click on the project (or on the Java class
corresponding to the main) and select Run As->Java Application.
