Hi Barry, realized that. Please do allow me sometime for formalize everything. You are absolutely right in that writing a new parser might not be a bad idea, but it is just soooo close for enabling Python to be used as the DSL language. We do not even need a DSL for HDL in this case, as Python can co-simulate with any HDL simulator that supports VPI/DPI/etc., but writing a full featured HDL is really just a few hundred of lines of code which enables you to throw away the entire HDL simulator (hundreds of thousands of lines, plus another hundreds of lines of glue code in between python and HDL simulator. Develop a dedicated parser eventually is NOT saving much more effort than using existing ones. And more importantly is the integration of Python and the DSL, as we want to use Python not only the write hardware, but write test for hardware which can be far more complex than the hardware itself. And python's ability to allow develop new test scenarios fast is the key here. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/TBZOIXY6GT53DVS2KSIG2CLVHWK3TSZK/ Code of Conduct: http://python.org/psf/codeofconduct/
