Problem Title:
OrCAD Capture 7.0: xnfmerge error 20 caused by invalid pin record with TIMESPEC symbol


Problem Description:
When using a TIMESPEC symbol in Capture 7.0, the software writes out XNF file with invalid PIN recor d. This results in error 20 with XNFMERGE program. You may get an error like this: ERROR 18 at line 22: Invalid PIN record.
       Missing or invalid direction field.

The XNF file written by Capture would have the following for the TIMESPEC symbol: SYM,U10,TIMESPEC,SCHNM=TIMESPEC,LIBVER=2.0.0,FROM:FFS:TO:PADS=10NS
PIN,DUMMY,DUMMY,DUMMY
END


Note that the PIN record is invalid in XNF syntax. It is a bug with XNF netlist writer in Capture 7.

Solution 1:

Delete the PIN record in the XNF file. So, it looks like:
SYM,U10,TIMESPEC,SCHNM=TIMESPEC,LIBVER=2.0.0,FROM:FFS:TO:PADS=10NS
END
