That wasn't it! I was just wondering if GHW is the best format for your purpose or if we could be developing an FST interface alongside your project. But apparently I wasn't clear. I don't see any other objection to using ghw, though I don't know if it's well enough documented. > I have a question: which waveform format in your opinion, is either > sufficient or could be extended to support a representation for analog > data (real arithmetic)? I have done insufficient reading on FST, but that's where I would start; it is supported by gtkwave already. One hobby horse of mine : VHDL has an excellent type system; I would want any interface to it to preserve that type information into the other domain (which domain is free to discard what it cannot use or support). An example of what I DO NOT want to see is the VHPI interface, which cannot transfer something as basic as an enumeration to a foreign function in a language which supports enumerations; because the interface is explicitly designed to some lowest common denominator without proper type support. That type support should naturally include real data and physical types to represent analog data. - Brian _______________________________________________ Ghdl-discuss mailing list [email protected] https://mail.gna.org/listinfo/ghdl-discuss
