How many LABs in Cyclone II (Logic Array Blocks)

Question

Hello,

I have a multi chain receiver in my design using a Cyclone II EP2C5, that works pretty fine.

Now I wanted to double the instances, and get an error that I would need 321 LABs and there are just 288.

Where can I find the that number of LABs in a document? I anyway wanted to upgrade to EP2C8, but I first need to know that there it works...

Thanks, Günter

there are 16 LE/LAB  2C5 4608/16=288  2C8 8256/16=516

Thanks a lot! Did not expect that this calculation is really true.  So my bigger FPGA will hold it.  Many many thanks! Günter

i would just change the device in your project and compile to confirm
