Hello Lionel, if i understand correctly you want to do heterogeneous verification with GHDL? I've done something similar in the sense that i'm cosimulating VHDL designs running in GHDL with other models running in MATLAB/Simulink, Open SystemC Initiative (OSCI) simulator or ModelSim. I think you should have a look at the VHPI interface. I plan to release some of my stuff before the end of june... But if you want to have a look at what i've done, i'd gladly send you an example written for an FIR filter. cheers, -Pascal -- Homepage (http://organact.mine.nu) Debian GNU/Linux (http://www.debian.org) LACIME: École de technologie supérieure (http://lacime.etsmtl.ca) _______________________________________________ Ghdl-discuss mailing list Ghdl-discuss@gna.org https://mail.gna.org/listinfo/ghdl-discuss
