Hi! I am using a Virtex2PV20, and one PPC core is used in my design. I drag a PPC Jtag controller core into the design in order to debug my SW code. however, I failed to program the device with the generated bitstream. iMPACT reports the DONE pin doesn't go high. In Bitgen, Jtag clock has been explicitly specified. I think the main reason of programming failure is that some wrong options were selected in Bitgen phase due to the fact that I am not familiar with how JTAG works. could someone guide me how to work out the problem? thank you! BRs.
