Simulating Triple Speed Ethernet, Decryption Fails

Hi Travis,

This is weird.

I believe our only difference is you are using Quartus Win version while I am using Quartus Linux version.

I don't want to rush into sharing with you linux cadence submodules files in case it create new issue .

Let me validate this issue with Quartus Standard v19.1 Win first.

Then I will get back to you.

Thanks.

Hi Travis,

It's good to know you got it working in Linux.

I need to find out more internally whether there is different sim tool support plan between Linux and Win or it's just purely a bug in Quartus Win

Thanks.

HI Travis,

I carefully read back the EDA support plan table from Quartus release note doc and finally found out the answer is there all the while. Sorry, I didn't catch it earlier.

Let me attached the screen shot and explain to you again.

• For Cadence sim (IES) for both Quartus std and pro, there is bracket (64-bit Linux only) – I understand now this is referring to support in Linux OS only
• If we look at Mentor Modelsim SE, it’s bracket (64-bit only) – this means it’s supported on both Win OS and Linux OS
• If we look at Aldec Active-HDL, it's bracket (32 bits win only) - this means it's supported in Win OS only

I hope I clarify your doubt now.

Thanks.

Dlim, thanks for looking into this further. I have to disagree with your assessment of Table 5 from the release notes. I believe it is referring to simulator support for launching the simulator from within Quartus. For example, going to tools/launch simulation library compiler. This makes sense since Cadence does not produce a Windows product.

But I am not trying to open Cadence from Quartus and it does not address the issue of the missing submodule files.

However when you look at the Triple-Speed Ethenet User guide v 19.4 page 171; both Cadence Xcelium and plain Cadence are listed as supported and it shows the files that should be produced. The Windows tool does produce those the files listed in table 111. However those files are useless without the submodule files that only the Linux version produces. So why would it produce some of the files but not all?

To summarize I still believe this is a bug. Since the Ethernet user guide shows Cadence as supported but the Windows version does not produce all the necessary files for this IP.

Hi Travis,

I have clarified with TSE engineering developer team.

• It's not a bug as TSE IP has no plan to support Cadence in Win OS as mentioned in Quartus release note doc.
• All Intel FPGA IP solution sim support plan needs to be align with Quartus support plan in general unless special clarified in respective IP user guide doc.

What you mentioned in both TSE IP user guide doc and IP sim generation script indeed is a flaw that Intel needs to improve on.

We are working internally to see how we can provide better clarification and user experience to customer moving forwards.

For now, I hope that you can move on with your project development using Linux OS first.

Thanks.

HI Travis,

Yup, I will definitely work out the improvement plan with Intel team internally.

Alright, I will be setting this case to closure shortly.

Thanks.
