I am designing a circuit which will be programmed into a Xilinx CoolRunner chip. I wrote the program in VHDL and simulated it with Alliance, and with the help of someone at Xilinx tweaked the syntax until it went through Webfitter and still works in Alliance. Unfortunately Xilinx does not support Linux, or any Unix for that matter except some huge and expensive system that they have at Boeing. Does anyone know enough about the innards of CoolRunners to write a VHDL compiler for them, and program them? phma
