Quartus does not generate files needed for Questa simulation seemingly at random

I have Quartus 23.1 installed on a Windows 11 machine and I'm trying to simulate a module that contains several Altera IPs and I am having some intermittent issues. Seemingly at random, when I star...

    Hi Juan,


    This is known issue before and had been bypassed with workaround. Please run only Analysis & Synthesis to perform RTL simulation instead of full compilation.

    Btw, RTL simulation actually needs only Analysis & Synthesis will do.


    Thanks,

Hi Juan,


Understood that. Will wait for the sample design.


Thanks,

    Hello,

    I have attached my dummy project full folder. The module has 4 IPs, NCO, LPM_ADD_SUB, and two different variations of the multiplier adder.

    I am unable to run the simulation because Questa complains the .vo file of one of the multiplier adder is missing. When I fix one, it complains about the other.

    Thanks for your help,

    Juan
