I am using WinCupl to program an ATF2500C CPLD, and the simulator shows a correct functioning, However, when I program the device, the 1, 22 and 40 pis no respond correctly. I am using a BK Precision programmer Mod. 866B. I am suspecting about any bug. I really appreciate any help. Thanks.

The Atmel simulator doesn't check everything

Jose,
You may need to look at the hardware docs and your compiled code document (*.doc), which tells you how many terms you used in each node equation. You are limited to 4 terms per node, otherwise you can't use all the internal nodes. If you have 5 terms on a pin node, for example, you cannot use the internal node next to it. If you do, the sim will work but your device will be a dud.

Good luck!

Andrew
