Differences in the use of Random Number Generator IP Core between Straitx IV and Arria 10

Simulate the Random Number Generator IP Core with ModelSim. The same testbench, when choosing different devices, the simulation results of rand_num_data are quite different. (1) When stratix iv (EP4...

Hi,

Thanks for your update. AS I understand it, you observe some issue when trying to run the simulation with the example that I shared to you. For your information, I have re-downloaded the zip sent to you and rerun the steps using Modelsim - Intel FPGA Edition 10.5b and the simulation seems to be working fine.

As I look into the error message that you have encountered, it seems to prompt about unable to compile "altera_mf_components.vhd". Based on my understanding from the msim_setup.tcl, if you are using Modelsim Intel FPGA Edition, it has built in library for this and the "ld" commands would not attempt to compile this library.

Just would like to check with you which specific Modelsim version that you are using to compile? If it is not Modelsim Intel FPGA Edition, you might need to edit the msim_setup.tcl to set the "QUARTUS_INSTALL_DIR" parameter correctly before you open and compile the files in Modelsim.

Please let me know if there is any concern. Thank you.

Best regards,

Chee Pin
