Error 19724: not enough LAB's for clock region

Hi PVanL,

You may try to use the Assignment Editor or by writing the command in QSF file to increase the size of the clock region.

Assignment Editor:

Go to Assignments > Assignment Editor, then in Assignment name column search for Clock Region and fill in other column details.

QSF file:

Open the QSF file and add the command you mentioned above to the QSF file.

Lastly, you may check out the following links to learn more about the clock region.

Hi Ven,

Thanks for answering, but this is what I found myself already. The issue is, I cannot find how to use the various commands.

Let me respond to your suggestions

1/ Go to Assignments > Assignment Editor, then in Assignment name column search for Clock Region and fill in other column details.

When I open Assignment editor, I get the following:

So,. There is not a “clock region” mentioned.

If I enter “clock Region” under “assignment name”, I get “yes” under enabled, in Entity “altera_eth_top”. What next?

And if it would have been there, what should I have filled in?

2/ Open the QSF file and add the command you mentioned above to the QSF file.

As I mentioned, I do not know how to use those commands in the QSF file:

1. I used set_global_assignment -name GLOBAL_PLACEMENT_EFFORT "HIGH EFFORT", without succes
2. quartus does not accept:set_global_assignment -name GLOBAL_PLACEMENT_EFFORT "OPTIMIZE FOR HIGH UTILIZATION", (Quartus removes it from qsf file)
3. I cannot find the syntax and parameters in set_instance_assignment -name CLOCK_REGION -to <to> -entity <entity name><value>
   I understand the syntax is something like -to “SX0 SY0 SX100 SY 100” (how to find the correct values?), and what are the values and syntax for <entity name> (is that “altera_eth_top”? or is that one of the entities below that?), and what is the value and syntax for <value>? I have no clue, and I cannot find it in a manual or example
4. I cannot find the syntax and parameters in set_instance_assignment -name CLOCK_REGION -from <from> -to <to> -entity<entity name> <value>,
   I understand the syntax is something like -to “SX0 SY0 SX100 SY 100” (how to find the correct values?), and what are the values and syntax for <entity name> (is that “altera_eth_top”? or is that one of the entities below that?), and what is the value and syntax for <value>? I have no clue, and I cannot find it in a manual or example
5. In the *.fit.rpt and *.fit.place.rpt report you can find:

Error (19724): Fitter requires 646 LABs for clock region in locations from lower-left (13, 32) to upper-right (37, 58), but only 621 LABs are available exclusively for that region

I have read that, but it does not explain how to repair this issue.

4/ Forum on solving the Error19724:

That is the link I gave to you, where the above suggestions under 2/ are given, but without guidance on how to use them

So, I hope you can give me more precise and elaborated help.

Thanks for your support.

Hi Pieter,

Can you attach the project file? So that I can look into the issue clearer and assist you with that.

Thanks.

Hi Pieter,

Thanks for attaching the files. However, can you archive your project, so that I can restore the complete project and ensure that no files are missing?

In Quartus, Open the project > Project > Archive Project.

Afterwards, you may upload the compressed .qar file. Thanks.

Hello,

I am porting OpenCL Stratix 10 BSP onto 1SG1100 based custom board (instead of 1SG2800) from the stratix 10 development board bsp. I have successfully generated by flat bsp flow. However when switch to base bsp flow I am receiving 4 19724 errors from the fitter. I have updated clock region as SX0 SY0 SX6 SX7 as reported by the flat bsp flow as maximum (It was SX8 SX11 for the 1SG2800 which I did not change initially). I am using Quartus 20.4.

The tail of the base fit.log is follows:
