Routing Resource Usage report per logic lock region.

[ALMSlinger]

Hello,

How do I report routing usage per logic lock region?  In the chip planner I can select the region and tool tip provides some information.  But I need a report for each region so that I can generate reports.

Thank you.
Best regards,

Sanjay

This should be in the Compilation Report after a full compilation of the design.

Thanks! But all I see is summary.

Check the Place Stage folder.

Hmm... Do you mean this?  This doesn't report the route statistics and congestion.  

It would be nice if I could obtain report of what we can see by hovering over the logic logic lock region in chip planner.

Thank you.

Best regards,

Sanjay

I'll check with the technical specialist to see if there's a way to check the routing utilization for the LL region.

Please expect slow response due to year end holiday.

As of now, I have not receive any update from the engineering team. 

I will continue to follow up with the engineering team and provide you with an update as soon as possible.

Thank you for your patience and understanding. Please let me know if you have any questions or concerns.

Unfortunately, we do not have the routing usage report for each Logic Lock region in the 'Compilation Report' .

As of now, you will need to hover in Chip Planner to check it.

I have filed a feature request and hopefully this feature will be added in the future Quartus release. Plan in 2nd half of 2025 (subject to change).

Since no further action is required from my side for this case, I will transitioning this thread to community support.

Hi @ALMSlinger 

The tool specialist is looking into adding this feature now, but just wanted to clarify a few things:

The only LLR-specific statistics that are currently reported are the "Logic Lock Region Usage Summary", regarding placed elements.

The most likely reason why the reports were done this way is that, while an element such as an ALM will fully sit inside an LLR, a wire can potentially pass through multiple LLRs depending on the length of the wire and the size of the LLR. In this case it becomes a bit difficult to report a useful representation of the routing utilization in any given LLR.

If you could clarify what exactly you were looking for from your requested report, and how you intend to utilize the report, perhaps it could provide some insight into what we need to add for this feature.

Richard
