How many LABs in Cyclone II (Logic Array Blocks)

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!

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