Ive already tried WEBpack ISE from Xilinx site. Ok to the schematic entry level system. But the MODELSIM simulator simply sucks! I have to edit manually all HDL files to generate a long simulation run. The HDLBencher locks my computer every time!! (My comp is ATHLON XP2000 with 512MB DDR, shouldn´t lock this one!!)
Im simulating a very lengthy state machine, about 26mS of vectors with 5nS resolution. Im not able to work with this HDLBencher. I ´ve worked with ALTERA MAX+ before and is far better from Xilinx tools. The problem with ALTERA devices is price (too high) and availability.
Anyway, what is the best tool to work with these chips???
