Intel DisplayPort Arria 10 Sample Project Not Simulating Correctly in Aldec Active-HDL

I expect to some transitions on rx_vid_sol, rx_vid_eol, rx_vid_sof, r_vid_eof, rx_vid_valid and rx_vid_data.

The only simulator I have access to is Aldec Active-HDL. The displayport core has a debug CRC setting that can be enabled to confirm the data received into the core. The sample design enables it by default. The User Guide shows that the CRC shouldn’t be 0.

I have tried to run this simulation using the pro version 18.1 and it still did not work correctly in Aldec.

Here is what Aldec prints out during the simulation: # KERNEL: start_main_link # KERNEL: start_test_main_link # KERNEL: Testing active line = 256 # KERNEL: Testing lane count = 4 # KERNEL: Testing Link HBR2 Rate (RX reconfig) # KERNEL: Testing Link HBR2 Rate (TX reconfig) # KERNEL: Testing maximum Vod and minimum pre-emphasis (TX analog reconfig) # KERNEL: Testing Link HBR2 Rate Training Pattern 1 # KERNEL: Testing Video Input Frame Number = 00 # KERNEL: Testing Link HBR2 Rate Training Pattern 2 # KERNEL: End Testing Link HBR2 Rate # KERNEL: Testing Link HBR Rate (RX reconfig) # KERNEL: TX Frequency Change Detected, Measured Frequency = 135 MHz # KERNEL: RX Frequency Change Detected, Measured Frequency = 135 MHz # KERNEL: Testing Link HBR Rate (TX reconfig) # KERNEL: Testing maximum Vod and minimum pre-emphasis (TX analog reconfig) # KERNEL: Testing Link HBR Rate Training Pattern 1 # KERNEL: Testing Video Input Frame Number = 01 # KERNEL: Testing Video Input Frame Number = 02 # KERNEL: Testing Link HBR Rate Training Pattern 2 # KERNEL: End Testing Link HBR Rate # KERNEL: Testing Link RBR Rate (RX reconfig) # KERNEL: TX Frequency Change Detected, Measured Frequency = 67 MHz # KERNEL: RX Frequency Change Detected, Measured Frequency = 67 MHz # KERNEL: Testing Video Input Frame Number = 03 # KERNEL: Testing Link RBR Rate (TX reconfig) # KERNEL: Testing minimum Vod and pre-emphasis (TX analog reconfig) # KERNEL: Testing Link RBR Rate Training Pattern 1 # KERNEL: Testing Video Input Frame Number = 04 # KERNEL: Testing Link RBR Rate Training Pattern 2 # KERNEL: End Testing Link RBR Rate # KERNEL: Testing Link HBR2 Rate (RX reconfig) # KERNEL: TX Frequency Change Detected, Measured Frequency = 40 MHz # KERNEL: RX Frequency Change Detected, Measured Frequency = 40 MHz # KERNEL: Testing Video Input Frame Number = 05 # KERNEL: Testing Link HBR2 Rate (TX reconfig) # KERNEL: Testing minimum Vod and pre-emphasis (TX analog reconfig) # KERNEL: Testing Link HBR2 Rate Training Pattern 1 # KERNEL: Testing Video Input Frame Number = 06 # KERNEL: Testing Link HBR2 Rate Training Pattern 3 # KERNEL: TX Frequency Change Detected, Measured Frequency = 135 MHz # KERNEL: RX Frequency Change Detected, Measured Frequency = 135 MHz # KERNEL: End Testing Link HBR2 Rate # KERNEL: Testing bpc = 1 # KERNEL: Testing Video Input Frame Number = 07 # KERNEL: SINK CRC_R = 0000, CRC_G = 0000, CRC_B = 0000, # KERNEL: SOURCE CRC_R = 0000, CRC_G = 0000, CRC_B = 0000, # KERNEL: Pass: Test Completed # RUNTIME: Info: RUNTIME_0070 a10_dp_harness.sv (1079): $stop called. Here is what is in the user guide: [https://www.intel.com/content/dam/altera-www/global/en_US/documentation/ufa1511788563556/ysy1475805841999.png]

I am trying to re-run it with Quartus 18.1 and Aldec 10.5a but am not hopeful that it will work. I am a little curious why the text output of the testbench in the user guide is different than mine. The user guide has a measured frequency of 270 MHz which my simulation does not have. My simulation has 135 MHz twice and the user guide has it only once.

I found the same: # KERNEL: Testing Link HBR2 Rate Training Pattern 3 # KERNEL: TX Frequency Change Detected, Measured Frequency = 135 MHz # KERNEL: RX Frequency Change Detected, Measured Frequency = 135 MHz # KERNEL: End Testing Link HBR2 Rate # KERNEL: Testing bpc = 1 # KERNEL: Testing Video Input Frame Number = 07 # KERNEL: Testing Video Input Frame Number = 08 # KERNEL: Testing Video Input Frame Number = 09 # KERNEL: Testing Video Input Frame Number = 0a # KERNEL: Testing Video Input Frame Number = 0b # KERNEL: Testing Video Input Frame Number = 0c # KERNEL: SINK CRC_R = 9b40, CRC_G = 9b40, CRC_B = 9b40, # KERNEL: SOURCE CRC_R = 9b40, CRC_G = 9b40, CRC_B = 9b40, # KERNEL: Testing Video Input Frame Number = 0d # KERNEL: Pass: Test Completed Thank you for the help!
