Hurrah! Good news everybody :-)
The AGA Minimig core with the TG68.C V4.0 (partial 020 compatibility) takes about 60% of the FPGA.
The aforementioned CPU core takes about 20% of the FPGA.
So plenty of room for expansion! :-) An entire AGA Amiga in around 1 million gates?
How is the TG68.C V4.0 in terms of performance on the Xilinx XC3S1600E?
