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.
I understand :-)
BTW, I was wondering: setting generics at elaboration time is rather late in
the compilation process AFAIK,
because the VHDL files are already compiled.
The whole design hierarchy would be compiled at elaboration time.
Would LTO be needed to obtain a notable speedup?
Well, it is not really LTO (in the gcc/llvm meaning), but the
possibility to have a whole view of the hierarchy.
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?
Yes, if you have time. Your feedback would be appreciated.
Tristan.
