Hi everyone.
As I'm making a CPLD board for the XC9572 5V CPLD from Xilinx I would like to know if it's possible to program this with a 3.3V compliant JTAG programmer from Digilent?
I mean, does the JTAG signals have to be 5V, if the chip is powered from a 5V source? Or can the JTAG signals be 3.3V, if I fx power the JTAG adapter from a 3.3V source and then connect the signals to the JTAG pins on the CPLD?

Best Regards
Thomas Jespersen
 

Hmm, so would this schematic work?
