"How to Connect 'Interrupt Sender' to Avalon Address in Platform Designer (Quartus Prime Pro)?"

Hi,

I checked and unfortunately this parameter has been deprecated in Quartus Pro beginning with Quartus Pro 17.0.

You will need to familiarize yourself with the latest custom component and implement it according to your design needs.

Thank you for your reply.

How can we avoid hard-coding the IRQ number for our custom interrupt request in the embedded software using Quartus Prime Pro 23.4? Ideally, we want to link this interrupt request to a parameter in 'system.h'. Since the IRQ number assigned by the Platform Designer changes with modifications, we need the embedded software to automatically reflect these changes from 'system.h', rather than manually updating the IRQ number in the code.

Hi

For the interrupt number and controller it is defined in the system.h file.

In the system.h under the interested IP the define for the interrupt number and controller number is defined there.

E.g. the interruptcontroller number and the number for the mSGDMA is define below.

Instead of hardcoding it, you could use the define int he system.h

Whenever you regenerate the BSP the system.h will be updated.

Hello,

Thank you for the reply.

Did you read the earlier messages?
We are talking about the "Interrupt Request" from a custom HDL module added to the Platform Designer. In earlier versions of Quartus, we could use the "Associated addressable interface" parameter to connect the custom "interrupt sender" to an interface and create a relevant parameter in "system.h," but it seems that this feature has been removed.
The solution that you mentioned only works with the "Intel IP Cores", and we are already familiar with this.

Hi

It seems like this could be an issue on the generation of the system.h macro.

For a custom IP there would be define generated in the system.h too.

Let us sort out this issue , but at the meantime is the interrupt number working if you hardcode the values in your code?

Hello,

Thank you for your response!

We couldn't locate a parameter corresponding to the "Interrupt Request" of our "Custom HDL Module" in the system.h file generated by the Platform Designer. Currently, if we use the "IRQ Number" assigned to this interrupt in the Platform Designer as a hard-coded value in our embedded software code, it works without any issues.

However, we would prefer a more flexible solution by associating a parameter in system.h with this interrupt. This approach would avoid manually updating the hard-coded value if we modify the Platform Designer in the future.

As mentioned earlier, in previous versions of Quartus software, we could achieve this using the "Associated addressable Interface" feature, which is unfortunately no longer available in Quartus Prime Pro.

Best regards.

Hi

Thanks for the confirmation that hardcoding value in code is working.

This issue is acknowledge by our team.

However they are currently looking into this and did not mention which version of Quartus this will be fixed.

Hi

If it is okay with you we will proceed to close this case.

Our technical team have yet to provide a targeted Quartus fixed version.

The issue number for the case for internal tracking is 15017381908.

At the meantime please use the hardcoded value for the time.

Hello,

Thank you for your response!

We confirm that it is fine to close this case. We look forward to the fix in a future version of Quartus.

Best regards.
