Hello everybody,
I am running into a fairly strange phenomenon in which I try and
program a CPLD, and although I can see my debug pins in my top level
bdf file as being there, they are also shown in the .pin file, all pins are tied to VDD when I measure with an oscope after programming the device.
Thus my question - how can I verify the contents of my programming configuration (pof) file ? I have also delted it and regenerated, strange that
I can program the CPLD but not get outputs on my debug pins.
Thanks a bunch -
Eric

Hi Eric,
look into the reports of your compile run. Did you get messages like pin xxxx stuck at VCC ?
Did you run simulation in order to make sure that your design behaves at intended ?
Kind regards
