How can a PLD go wrong? The TA watched me burn it (with Dataman) but then when i connected my circuit it did not light my 7-input LED. So, my question is how to check it... for some reason i don't belive that PLD is fried, because i used my friend's (burned it for my truth table) and it did not produce any output either. Circuit is pretty simple and i am pretty sure it is working fine. Thanks much.
