May I ask why? I'll explain : there has been some discussion of adding support for another wave format : possibly FST : to ghdl as an alternative to ghw (currently ghdl/gtkwave only) and vcd (more widely used but not ideal for VHDL). I'm wondering if it might be time to bring that forward, but don't expect it to happen instantly... - Brian _______________________________________________ Ghdl-discuss mailing list [email protected] https://mail.gna.org/listinfo/ghdl-discuss
