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

Altera_Forum · ‎06-23-2014

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.

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:

Try reducing your logic if you can, and or setting the optimations for space versus speed. That may at least get you to fit.

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