Firt time starts a full FPGA-Minimig on the DE2-Board without external CPU and PIC. I use SDRAM and a CPU-IP-CORE. The CPU-Core ist software but not timing kompatible. Thats why make some Demos Problems.

I just finished checking this option out.  In a word, can't be done.  The EP2C35F672-C6 FPGA it utilizes only has 32,000 gates.  The MiniMig's FPGA is 400,000 and is 80% utilized.  In short, the chipset alone won't fit into the design.

The EP2C35 FPGA on the DE2 has 32,000 LE's (CLB) and 4Mbyte RAM!!

The XC3S400 used on the original minimig board has 896 LE's and 288Kbyte RAM!

Which one do you think is better?

Read before posting ;-)


I did read, just read the wrong column.  Sorry for that, but it did bring the topic back to life.  8)

But I still was unaware that there was a freely available 68000 core available out there.  If so, perfect system I'd have to say.
