ModelSim Exit code 211 with CycloneV Fractional PLL

Hello, I'm trying to simulate on ModelSim Intel-FPGA Started Edition 10.5b a design that was compiled on Quartus Prime 18.1 on the CycloneV. The design compiles correctly, and the EDA netlist Writer...

Could you try to run the simulation using the Nativelink simulation flow?

Additionally, could you try using Questa Intel FPGA edition (starter/non starter) as Modelsim has been replaced by it.

If the issue still persists, could you share the project and testbench so I could try to duplicate the issue and find a solution.


Regards,

    Hi Richard,

    Thanks for the reply.

    I have attempted to run the same project on Questa Intel FPGA started edition 2023.3 for the Quartus 2023.1 without success (I get error message

    "Error $MODEL_TECH/../intel/vhdl/src/cyclonev/mentor/cyclonev_atoms_ncrypt.v(38): in protected region" which means the command vsim name does not work.

    I think I tried the simulation flow you've asked without any success.

    I'll attach a very simple project which seems to give me these issues (it's a simple PLL with 3 output clocks). The problematic file is in Simple_PLL/simulation/modelsim/e_Simple_PLL.vho, in particular the entity mapped in line 261 is the one that makes Modelsim crash.
