Compilation Error for Board Test System (Cyclone IV GX XCVR sample)

[Altera_Forum]

Hi All,  

I am trying the get to a starting point where I can have the source code complied and run it successfully onto the board. When I build the source project, it gives me: error (170012): fitter requires 902 labs to implement the project, but the device contains only 900 labs.  May I ask how to resolve this issue or what's the cause of this problem?  Any pointers would be very helpful.   Thanks, Leon.

Hi Leon 

  --- Quote Start ---  error (170012): fitter requires 902 labs to implement the project, but the device contains only 900 labs.    --- Quote End ---    Basically is saying you are out of resources. LABS are blocks of LE's with routing. So If you have enough LE's then it may be a routing resource limitation.  You can read up more on LE's and LAB's in this document: http://www.altera.com/literature/hb/cyc3/cyc3_ciii51002.pdf  Try reducing your logic if you can, and or setting the optimations for space versus speed. That may at least get you to fit.  Pete

Thanks Pete, I reduced my ram to 13*16 (from 14*32), this seems to fix the compilation problem .
