Re: how to test CPLD

I use CUPL to make CPLD content. For programming I have VP-880 from Wellon. The CPLD test I do on breadboard. The CUPL has also a software simulator, but the test on breadboard is more secure and fast. If I test a chip select decoder, I need only DIP switches and logic probe or LED diode. If I test ...
