Not able to do fitting design with Quartus 22.1

Hi Vikram,

By comparing between the 19.1 and 22.1 .qsf, there're much differences in partition assignment may be have to recheck on this.

The error message suggests that have to reduce the combinational node in order to fit.

Thanks,

The problem still exist in 22.1 and in all later versions of Quartus after 19.1.

So for us the last working Quartus software is 19.1.

I appreciate, if Intel Quartus team have a deep look in to it and get back to us with latest working version.

Hi,

I had compared between the v19.1 and v22.1 .qsf and noticed there're differences between the v19.1 and v22.1 .qsf. in terms of partition and logic lock region. Is that the design used in v19.1 and v22.1 are exactly the same? Is that the partition and logic lock region are exactly the same as well? If no, then that's normal to get different compilation result for both v19.1 and v22.1.

Thanks,

Yes, the status is same. 22.1 we're not able to use.

Hi,

So you mean the design used for both 19.1 and 22.1 are exactly the same? But why the .qsf provided for both 19.1 and 22.1 showing differently at the partition and logic lock assignment? In GUI, can you go to Assignments -> Design Partitions Window and Logic Lock Regions Window to confirm about it.

Need to make sure the design used for both 19.1 and 22.1 are exactly the same.

Thanks,

Hi, yes design is exactly the same. Partition is not the issue, with/or without partition assignment just trying to fit in 19.1 goes well without any issue. With later than 19.1 Quartus (including latest 21.1), we seeing the error we mentioned.

So we like to know, to fit in later version of Quartus than 19.1 what changes in qsf we need to do.

Hi Vikram,

Forgot to mention I also noticed that there're different at this setting Auto Packed Registers. Version 19.1 use 'Normal' while version 22.1 use 'Minimize Area'. Make sure fitter advanced settings are the same as well.

Thanks,
