Hi all,I am facing a problem that is not going away in any way. The problem is when ever I compile my design it gives the following error: Can't place 37 pins with 2.5 V I/O standard because Fitter has only 32 such free pins available for general purpose I/O placement. Well, I have changed few banks to other voltages. Then it begins to complain about other voltages, the same way. I am following a tutorial and using their ready made .csv file for pin assignment(importing .csv file). This project involves creation of schematic and generation of a Qsys system and then placing the symbol of Qsys system(NIOS II processor) in the schematic. It worked very fine for few days. Then I changed the Qsys file(according to the part 2 of the lab), and then it stopped working all together(failing to compile since than. Till part 1 of the lab it was working fine. So I again started project (lab 1) many times, but even lab 1 is not working now, and same fitter problem. Please see the attached file also. Should I clean things on system level? if yes, then which files should be deleted or option should be changed. Any body any guess?
