Hi,
Your resource problem is the logic, not memory blocks as indicated by the error message(LABs).
The notion of 85% or so is sort of rule of thumb for fmax. The fitter doesn't follow this rule. It will fit as long as there is resource until 100% if necessary.

Hi
I do have a problem with compilation when setting the on-chip RAM to 60kb on a Cyclone 3c25. I once did that and the project compiled without any problem. But now it wont work even in a simple project. I only intend to use on-chip memory to use 'fopen' and 'fclose' in my C code. I dont know what could be the problem if it did work once. Please help.
