Failed to execute Ideal Dispatcher mode #320

Open Vinay0203 opened 4 months ago

Vinay0203 commented 4 months ago

I am trying to execute fmatmul program in Ideal Dispatcher mode.

The steps i have taken is : 

  1. cd apps
make bin/fmatmul.ideal

    and the output got is : 

    
cd fmatmul && if [ -d script ]; then python3 script/gen_data.py 128 128 128 > data.S ; else touch data.S; fi

4. I am trying to achieve fst file only for the vector unit 'ARA' which does not include signals from CVA6 {or} some extra signals which are dedicated to ARA along with the CVA6 signals
So if we get a trace file in Ideal Dispatcher mode is it the trace file only generated by ARA alone and only that signals? Am i thinking correctly? 
and what is the command modification to get trace file after solving this issue , is it just by giving command as :

make simv app=fmatmul ideal_dispatcher=1 trace=1

mp-17 commented 4 months ago

Hello @Vinay0203, Also other users reported issues with the Verilator traces. I will need some time to check this out since we use Verilator only in the CI with no traces and no ideal-dispatcher mode. If you have a QuestaSim license instead, it should work out of the box

Please comment on the point 4. illustrated in previous message
