Hi, > How do you proceed with commercial simulators ?
I don't xD Actually now I know for sure GHDL is much faster (at least gcc version, at simulation), I rarely use commercial simulator. Mostly to do a quick test with direct instantiation of bare FPGA primitives, to not bother bother with simulation models and libraries. I much dislike commercial solutions because users rarely have similar versions/licenses available. It's irritating when working with other people. > > On one hand, I think being able to set some generics with -g at elaboration > > time can have a positive impact, > > on the generated simulator speed and on the generated executable size. > > Yes, that's the idea. > This is not really a maintainance issue but a way to speed-up simulation. BTW, I was wondering: setting generics at elaboration time is rather late in the compilation process AFAIK, because the VHDL files are already compiled. Would LTO be needed to obtain a notable speedup? > Did you try the mcode version ? With it, code is generated only with -r > > (or with --elab-run). No I haven't tried it: it's not a durable solution, simulation speed (again), and I haven't got much time, so not much motivation. Should I?
