FYI, and you may know, but i've not tested actually, some closed source VHDL simulators (such as Aldec Riviera-PRO) have relax options (e.g. integer range), IIRC. consider to introduce these kind of relax options to GHDL? _______________________________________________ Ghdl-discuss mailing list Ghdl-discuss@gna.org https://mail.gna.org/listinfo/ghdl-discuss
