STRATIX 10 PCIE + HARD IP ERROR WHILE SIMULATING EXAMPLE DESIGN ON MODELSIM

[rsing108]

Hi,

I am trying to simulate the Avalon memory mapped Intel Stratix® 10 Hard IP+ for PCIE example design for Stratix 10 MX by following the instructions of https://www.intel.com/content/www/us/en/programmable/documentation/sox1520633403002.html#xvu1520633284604, but while running "ld_debug" command I am getting errors like 

# ** Error: /tools/Intel/quartus_pro/19.3.0.222/quartus/eda/sim_lib/ct1_hssi_atoms.sv(5646): Questa has encountered an unexpected internal error: ../../src/vlog/vgenexpr.c(12502). Please contact Questa support at http://supportnet.mentor.com/
# ** Error: (vopt-2064) Compiler back-end code generation process terminated with code 2.

I tried this using both quartus pro 19.3 and 19.4.

my modelsim version is 10.5c

Also, attaching the full transcript.

Hello Sir,

I tried to generate the STRATIX 10 PCIE + HARD IP example design and run in modelsim, I can run successfully. Below is the transcript.

Look on the error on your side, seem like the error is generate from the simulator but not the IP file. You should contact the simulator (mentor) for help.

Thanks @BoonT_Intel ! Can you share what version of modelsim and quartus you are using?

[BoonT_Intel]

Hi Sir,

Here is the version.

acds/20.2/50,modelsim_se/2020.2

[rsing108]

Thanks @BoonT_Intel . I think there is an issue with the modelsim version 16.5c I am using. Will try updating to a newer version and post an update. Thanks for you help.

[BoonT_Intel]

Noted and thanks.

[rsing108]

Updated my modelsim version to 10.6g. The issue is fixed now. Thanks @BoonT_Intel for all your help.

[BoonT_Intel]

Good to know. Thanks.
