Virtex2PV20 programming failed, DONE pin doesn't go HIGH

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.

You need to add both PPC in your device to JTAGPPC as documented on pg.

117ff in the "PowerPC 405 Processor Block Reference Guide".
