Hi everyone, I was going through the OrCAD Capture Tutorial designing the full adder circuit using 2 half adder hierarchical blocks. My problem is when I try to cross reference the full adder design I get the following errors:
INFO(ORCAP-1399): Performing Cross Reference.
ERROR(ORCAP-1800): Duplicate Reference: U2A.
ERROR(ORCAP-1800): Duplicate Reference: U1A.
ERROR(ORCAP-1800): Duplicate Reference: U3A.
Basically my issue is that each hierarchical half adder block refer to the same reference designators for the half adder schematic parts. How do I resolve this issue?
Thanks for everyone's help!
