If your using Licom (which i suspect not unless you have alot of money to burn and mass manufacture) you must have the £9,000 parralel dongle to go with it ? we use this at BHW Components and is used for precision engineering - nesting jobs and sending them to Computer Numerical Control machines........
ALTERA make programmable logic chips, do they have a software package too then?
It depends what you want Gaz, if you want something for designing circuits and simulating their operating, finding out voltages, waveforms, etc then use Electronics Workbench software.
If you want PCB manufacturing capabilities, then either use Electronics Workbench Multisim followed by Ultiboard/Ultiroute or some other package.
