Not able to do fitting design with Quartus 22.1

Hi,

I have indeed used Normal settings for Auto Packed Registers. Attached is the freshly generated reports with 22.1.

The problem is still the same.

Please check if anything in the settings need to modified.

Hi,

Then I think probably have to get a larger device. Migration from 19.1 to 22.1 most likely will involve many things being upgraded which probably will cause higher utilization. So now I got both fit reports of 19.1 and 22.1. By comparing between Fitter Resource Usage Summary of 19.1 and 22.1, clearly can see that it's quite full for 22.1 compared to 19.1 even ALMs utilization (114%) also had been exceeded 100% (image below). I would suggest that getting a bigger device.

Thanks,

Hi,

I reckon, this is not the solution I am looking for. If its easily fits in earlier version of software, then all that we can conclude is the latest version of software have bug.

So unless Intel comes back with proper fix of the bug we can't use the latest software.

How about try with the settings below and see:

Optimization Mode:

Area

Advanced Fitter Settings:

ALM Register Packing Effort - High

Fit Attempts to Skip - 2

Perform Logic to Memory Mapping for Fitting - on

Perform Physical Synthesis for Combinational Logic for Fitting - on

Placement Effort Multiplier - 4.0

Auto Packed Registers - Minimize Area with Chains

One more is can you try to do another migration totally without any ip upgradation by ignoring the IP Upgrade Recommended box. Any difference?

Thanks,

Or try go to Project -> Clean Project and see

Hi,

Clean build too gave the same error.

Hi,

Could you provide the 19.1 design for bug identifying? Design is needed for engineering team to identify the bug as well.

You can provide the design privately to my email qi.sheng.ng@intel.com and will be treated confidentially.

Thanks,

Hi,

Any further update or concern on previous post community.intel.com/t5/Intel-Quartus-Prime-Software/Not-able-to-do-fitting-design-with-Quartus-22-1/m-p/1508355#M79463?

Hi,

We're still unable to use the Intel latest software. For now we will keep using the old 19.1 version.

We hope Intel does fix this bug in future releases and then we will try to migrate to the new version of software.

Vikram
