Also such companies like Cadence and HP have developed own software systems leveraged by the Ptolemy technology. Actually, there are two different Ptolemy platforms now: Ptolemy II and Ptolemy Classic. Professor Lee's Ptolemy group in Berkeley is really doing a great job (Thanks to all involved!) and I guess they are rather focussed on the new Ptolemy II project now. I am still developing under Ptolemy Classic and I am using it for model implementation, simulation and design of photonic transmission systems (WDM). If there is no commercial tool which is readily designed for your purpose already then Ptolemy might be the right choice for you. It is a great open framework to implement new modules (Stars), interfaces, and models of computation (Domains, Targets) and it runs under all important operating systems.

Re: Ptolemy fails to compile
Hi Wolfgang, Thank you very much for your answer. It seems you are the only one who is working intensively with Ptolemy at the moment. Is it true? I made the few changes in ptlang.y, and now everything works well. Please let me introduce my job. I'm working for a European Program which aims to build a Framework for Digital Signal Processing System development. The Framework should help us to reduce the time to market of our products (hardware and Software) and also to reduce the time for redesign in case of component obsolescence. Ptolemy is one of the candidate Tools (sorry, I know that Ptolemy is a Framework, but...) and I have in charge to evaluate this tool by the end of September '99. Therefore I will probably need more help...

Hi:
That sounds like you hit the ACS ptlang bug which will occur only if your shell
lacks the PWD variable (e.g. Bourne shell). On Solaris this bug will cause
ptlang to crash with SIGSEGV when trying to process ACS stars (see comments in
the attachment). I already sent the attached stuff in January and the 2nd patch
(pt0.7.1p1.ptlang.patch.gz) will fix that ptlang bug.
Best regards,
Wolfgang.

Re: Ptolemy fails to compile
What is the exact failure? Can you include the log of the compilation around the point of failure? -Christopher Hi all, I tried to build Ptolemy 0.7.1p1 from scratch (including GNU Tools) on SUN Sparcstation4 Solaris2.5.1 and I didn't succeed because ptlang failed to compile the ACS domain stars (files with corona statement only).
