error in compiling the RapidIO IP for Stratix II GX: EP2SGX90FF1508C3.

Honored Contributor II



I generated the rapidio IP from the MegaWizard Plug-in Manager for the device Stratix II GX: EP2SGX90FF1508C3. 

It generated the codes corresponding to the parameter specified in the MegaWizard Plug-in Manager then I added all the 

codes generated to the quartus project. Then I compiled, during compilation the following error came 


Error: Can't place 730 pins with 3.3-V LVTTL I/O standard because Fitter has only 653 such free pins available for general purpose I/O placement 

Error: Can't place pins due to device constraints 

Error: Can't fit design in device 

Error: Quartus II Fitter was unsuccessful. 3 errors, 12 warnings 

Error: Peak virtual memory: 432 megabytes 

Error: Processing ended: Wed Mar 09 15:29:40 2011 

Error: Elapsed time: 00:00:29 

Error: Total CPU time (on all processors): 00:00:29 

Error: Quartus II Full Compilation was unsuccessful. 5 errors, 36 warnings 


I am new to Quartus software please help me in solving this error.......

Your design is using to many input/output ports on the FPGA. Try to reduce them. 730 ports is a lot...

Thank you for your advice  

I regenerated the IP using MEGA WIZARD with the different parameter and recompiled the design successfully :)
