Large open source FPGAs?

You could try LEON, a Sparc processor with AMBA and peripherals:

Hi

Well, "open source FPGA" is an abuse of language, a fpga is a hardware piece. The "cores" or "IP blocks" you program/load in them are open sources.

If you're just looking for a "big" thing. Look at gaisler leon 3. It's a complete SoC solution with differents cores in it, you can surely configure it to become pretty large. And it's also more "polyvalent" since you have cpu core, memory controller, pci , ...

I should have known that; thanks for the pointer. Nothing beats looking like a n00b...

That might be interesting. My rationale for looking for something "big" is that I would like to have reasonably long run times. The USB2 controller I was working with took under a minute to synthesize. One of the problems is that I would like my workload to be as 'real world' as possible, and testing EDA tools with tiny chips isn't very interesting for those who really are using them for work.

I don't really know enough FPGA's to explain, but for an ASIC, I am pretty sure that the time to do an extraction for a 1mm^2 chip will be almost entirely uncorrelated to the time for an extraction of similar quality on a 370mm^2 behemoth. The real issue is trying to get a realistic workload and my feelings are that most of what I have seen at opencores.org are 'small'. Thanks for your help everyone I appreciate the comments!
