expand　On-chip memory

I am using Quatus18 to program in Nios. The device is a Cyclone 10CL025Y. I have increased the on-chip memory in Platform Designer because of the size of the program, but I cannot compile it in Qua...

Hi,


May check on this document link https://www.intel.com/content/www/us/en/docs/programmable/683777/current/embedded-memory-capacity.html

The RAM Capacity (Kilobit) for device Cyclone 10CL025 is 594 Kb which equals to 74250 Bytes. Can check whether the device has enough memory size by going to report Fitter -> Resource Section -> Resource Usage Summary

You can also try on device with larger memory size (Cyclone 10CL040) and see whether the problem still persist.


Thanks,

Best regards,

Sheng

Hi, Mr. ShengN

I checked the report.
Total Memory for M9Ks is 608256.
Can the On-Chip Memory value be used up to 608256?

The report is noted below.

Rest regards,

Kenichi
