Hi,

I did internal searching and found that the simulation tools supported for VCS Quartus version 19.4 is O-2018.09-SP2-2 (64-bit Linux only).

Can you try to swicth to vcs 2018 sp2 and see if the error still replicate ?

Regards,

Aida

    Hi Aida,

    I see the same problem while simulating the EMIF design which does not contain the HPS core. I am using xcelium2019.09_s007 and here is the error I see during configuration:

    170038 ns: ERROR: iossm_bf_cpu_cpu_test_bench/ihp_read is 'x'

    Simulation stopped via $stop(1) at time 170037750 PS + 3

    xcelium> exit

    Can you help with this?

    Thanks,

    Naved

      PS: The device is Stratix 10 GX which anyway does not have HPS and the Quartus version is 19.4.

      Hi @alinave​ ,

      Sincerely sorry for the delay due to long holiday in my region.

      Have you try to used this supported tools version for Xcelium for Quartus 19.4?

      Regards,

      Aida

      Also may I know which memory simulation model are you using (for example Micron or etc)?
