Hello,

What kind of relay-logic circuits are you looking to replace? If your circuits are simple enough, a good FPGA will suffice. They are not very hard to program, I have used a program called WinCUPL with them. I have only worked for a short time with them, but they sure beat using arrays of gates.

Also, I will suggest you take a look at Circuitmaker. It is a very useful tool for people working/learning/messing around with electronics. There is a student version of Circuitmaker 6 available for free on the Microcode website. There is also a trial version of Circuitmaker 2000 available (30 days only). I have used both the student version of Circuitmaker 6 and the full version of Circuitmaker 2000, and there aren't many differences between them.

PM me or IM me if you need any help and Good luck.
