Has anyone out there had success instantiating chipscope cores in XPS? I have a V4FX design that builds with no problem. Then I instantiated chipscope_opb_iba and chipscope_icon. Now when I build I get the following error:
ERROR:NgdBuild:455 - logical net 'net_gnd0' has multiple driver(s): pin G on block XST_GND with type GND pin O on block chipscope_opb_iba_0/chipscope_opb_iba_0/i_cs_coregen_chipscope_ opb_iba_0/cs_coregen_chipscope_opb_iba_0/i_no_d/u_ila/u_dout with type LUT3 WARNING:NgdBuild:452 - logical net 'chipscope_icon_0/control0 has not driver
I am new to xps as well as chipscope, so it is probably a newbie error. I couldn't find anything in the answers database or usenet archive.
revs: ise: 8.1.03i xps: 8.1.02i cs: 8.1.03i
Someone in another thread mentioned "wiring up" the chipscope_icon core. How does one do that? All I could figure out how to do was go to system assembly bus interface view and connect chipscope_opb_iba to the OPB.
thanks, Jeff
