When instantiating the IBA/OPB core in my design, I receive the error:
"ERROR:NgdBuild:76 - File "d:\project\ppc_chipscope\projnav\_ngo\iba_opb.ngo" cannot be merged into block "i_iba_opb" (TYPE="iba_opb") because one or more pins on the block, including pin "m_dbus<0>", were not found in the file."
The work-around is to delete "m_abus" and "m_dbus" from the instantiation template generated by ChipScope Generator.
1. Generate the IBA/OPB core from ChipScope Generator.
2. Generate the example file (VHDL or VERILOG).
3. Open this file, and comment out the "m_abus" and "m_dbus" signals present in the IBA_OPB declaration and instantiation.
