[Coco] Coco Digest, Vol 87, Issue 8

Compile/Synthesis time is dependant on the design, which FPGA/CPLD used, as well as the 
computer. I would almost think that OS has some impact also. As for the computer, the more 
RAM the better. Large designs need a huge amount of RAM or huge swap space on the disk. 
Still swap space is far slower than RAM.
