Why does Mentor* ModelSim simulation of the Intel® FPGA Triple-Speed Ethernet IP core design example run forever?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition version 19.2 Software, the Intel® FPGA Triple-Speed Ethernet IP core Design Example MAC + 2xTBI PCS + E-tile PMA variant, when the "Enable E-tile transcevier dynamic reconfiguration" option is selected,  Mentor* Modelsim simulation will run forever.

This is due to the Intel® Stratix® 10 E-tile Avalon Memory Map reconfig_clk and reconfig_reset ports not being properly connected in the design example Mentor* Modelsim simulation test bench file.   

Workaround/Fix

To work around this problem in existing releases of the Intel® Quartus® Prime Pro Edition of software, modify the following Mentor* Modelsim test bench files

  • <tse_design_example>\testbench_verilog\<tse_example_design>\eth_tse_0_testbench_tb.v
  • <tse_design_example>\testbench_vhdl\<tse_design_example>\eth_tse_0_testbench_tb.vhd
  1. Declare the following Avalon-MM reconfig ports as wires (wire reconfig_clk_0, wire reconfig_reset_0, wire [18:0] reconfig_address_0, wire reconfig_write_0, wire [7:0] reconfig_writedata_0, wire reconfig_read_0, wire [7:0] reconfig_readdata_0 and wire reconfig_waitrequest_0)
  2. Assign reg_clk in the testbench to reconfig_clk_0 and reset in the testbench to reconfig_reset_0.
  3. Tie the following signals to 0: reconfig_address_0, reconfig_write_0, reconfig_writedata_0 and reconfig_read_0.

This problem is fixed starting from the Intel® Quartus® Prime Pro Edition v20.3 software.
