Using Quartus 17.0.2 EDA Netlist Writer crashing

Hi,

Can you provide your qar file so I can reproduce your error? To do this, go to Project->Archive Project...

Thanks,

Nurina

FYI, this also applies to 20.1.1. Same project, seemingly same error message. See below:

Hi,

Thank you for providing your project file. I've reported this issue to engineering.

Nurina

Hi,

Engineering suggests the following workaround:

Remove the RESERVE_PIN AS_BIDIRECTIONAL assignments from the QSF if the pin is not used by the design.

The fitter won't create IO buffers to implement the BIDIR if they are not there.

Let me know if this solves your problem.

Regards,

Nurina

Well, that's a bit of a frustrating workaround. We really don't want to keep changing the QSF file for the board based on whether we're using a given pin at a point in time or not.

Hi,

Unfortunately this is the only available workaround.

With the RESERVE_PIN_AS_BIDERECTIONAL assignment, Quartus will create IO buffers and quartus_eda will try to connect the IO buffer to the pin whether or not it is used. If unused, Quartus will assert for the pin to be used and you will come across this Internal Error.

Apologies on the inconvenience.

Regards,

Nurina

Hi,

The bug has already been fixed for Quartus Standard version 21.1.

Regards,

Nurina

Can you let me know if this solves the Internal Error?

Hi,

We did not receive any response to the previous question/reply/answer that I have provided, thus I will put this case to close pending. Please post a response in the next 15 days to allow me to continue to support you. After 15 days, this thread will be transitioned to community support. The community users will be able to help you with your follow-up questions.

Regards,
Nurina

PS: If you find any comment from the community or Intel Support to be helpful, feel free to give Kudos.

The Lite edition is still stuck at 20.1.1. This issue will remain open until you release 21.1 to Lite.

Thanks,

Alex
