Transceiver Native PHY simulation error

I got some problems in simulating Native PHY recently,after compiling all the necessary design files, i can not excute simulation due to following errors: how to solve these errors,and any...

    Hi,


    For your information, the Native PHY can perform automatic word alignment if the RX word aligner mode is configured to “synchronous state machine”. I believe the example that you are having might be using manual alignment mode.


    Sorry for the inconvenience.

Hi Kavin,

As I understand it, you encounter some issue running simulation with Native PHY. As I look at the screenshot, seems like the simulation error is related to the reset controller module. Would you mind to further elaborate on the specific steps that you are taking to compile the reset controller libraries and the files that you have compiled?

Just wonder if you have had a chance to try the following:

1. Try with other Quartus version ie the latest Q20.2Pro to see if similar issue occurs to narrow down Quartus version dependent issue.

2. I notice that you seems to be using simulator tool other than Modelsim. Would you mind to try with Modelsim AE to see if similar issue occurs to narrow down to simulator tool dependent issue.

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


Best regards,
Chee Pin

    Hi Chee Pin，

    Glad to hear you.I use Questasim 10.2c to simulate Native PHY on Arria 10 deveices.When the IP is successfully generated, a folder named sim will be generated in the root directory. When compiling the simulation library, I compiled all the HDL files in the sim folder, and the compilation results showed that they were successful. Then I generated the simulation file to start the simulation, and the errors mentioned before appeared. I also tried to compile according to the order of loading files when QSYS was compiled, but it did not improve.

    1.I have tried both versions of quartus 17.1 and 18.1, but there is no improvement. License will be a problem for 20.2;

    2.Qustasim is nearly the same with Modelsim,but I will try with Modelsim latest version.

    3.Is it possible for you to help me use the latest version of quartus to generate a Native PHY design example so that I can use it to check my simulation problems.

    Best regards,
    Kavin
