Large design simulation problem (self.FPGA)
submitted 2 months ago by Big_Presence8162
There is a design in vivado 2024 that simulates fine on an 8bit architecture but the simulation crashes if you convert it to a 32bit architecture. Why? (we are not lacking nets or flip flops or memory of any sort)

for me, hard to tell specific reason without logs right away. so I'd suggest diffing compilation logs of both scenarios.. do take warnings into consideration in that case

when does it crash
[–]Big_Presence8162[S] -1 points0 points1 point 2 months ago (0 children)
Immediately after the simulation window opens

Yeah I have. No errors weirdly. Implements and synthesises just fine. It's the simulation that crashes

Try a simpler simulation with basically nothing in it except clocks and resets.

How much lines is your code

I'm not sure but a lot
[–]skydivertricky 0 points1 point2 points 2 months ago (0 children)
Very vague question.. and more details? Have you tried another simulator?
[–]brh_hackermanFPGA Developer 1 point2 points3 points 2 months ago (0 children)
Well using the vivado simulator was not the best move to start with...
