Hi
I'm new in CPLD and FPGA world I have an application with XC9572 in PC84 package. My problem is that if I make "and" from two signal and "nand" from the same signal I have the right wave in output simulation (one inv to the other), but when I make this in the phisic CPLD I have the same output not inv (like nand operation)!!!! I have make this with isewebpack 7.1 and its schematic editor. Can you help me? I thanks all previusly fabicenn |
