Hi Peter,
Thanks for the reply.
I'm looking for something along the lines of Simulink Coder:
http://www.mathworks.it/products/simulink-coder/description5.html
The purpose is to use OpenModelica to define some blocks of
a system in terms of FSMs:
https://en.wikipedia.org/wiki/Finite-state_machine
These should be:
** simulatable within OpenModelica the usual way;
** exportable (e.g., as a stand-alone C function) that I can
then wrap and include in a completely different (embedded)
system (e.g., a wireless sensor node -- WSN).
In other words, I try to use OpenModelica as high level
functional input environment (e.g., for developers with no
programming skills), with:
** testing capabilities (usual OpenModelica simulation);
** export capabilities (standalone C code generation).
By these I mean something like:
-- FSM conditions be encoded as either plain C 'if' or calls
to functions that compute them -- these functions should
be generated alongside the FSM C code;
-- FSM states are decoded using C 'switch' or equivalent
constructs;
-- the I/O ports of the OpenModelica block are encoded in
C as, e.g., function formal arguments (one of these may
be the system time, if needed).
We intend to use this flow and models as part of a free software
high level synthesis of WSN applications. The developer should
be able to input the top-level operation of a WSN node, such as:
'every minute read the temperature from port T and send
it to the average block on port Ain. Every 60 minutes
read the output of the average block from port Aout and
send it to the radio input port TX for transmission'.
Is there an OpenModelica export functionality close to this
that I can use and, possibly, adapt? The API of the generated
code is not critical, but the code should be self-consistent --
it should not make references to simulator or other external
libraries.
I hope this is more clear. Let me know if you need more info.
Thanks,
Mihai
