xnf2wir error 214: pin names for <component> do not match Viewlogic symbol
描述
When xnf2wir gives error 214, it means that it has either found a symbol in the xnf file that it does not understand, or it has found a symbol with pins that don't match its description of the pins on a symbol of the given type.

Improper setup of libraries in the viewdraw.ini file can cause this. At the end of the viewdraw.ini file you should only have the primary, appropriate part family, builtin, and xbuiltin libraries uncommented (remove the pipe symbol), in that order.
It is very important that primary be the first and builtin and xbuiltin be the last libraries in the ini file. Here is an example of a correct library setup for a PC:
DIR [p] . (primary) DIR [M] C:\PROSER\UNIFIED\XC3000 (xc3000) DIR [M] C:\PROSER\UNIFIED\BUILTIN (builtin) DIR [M] C:\PROSER\UNIFIED\XBUILTIN (xbuiltin)

One old cause of this is the presence of a hard macro in the design (search for "DEF=HM" in the xnf file to see if there is a hard macro in it). If this is the case and you are still using the pre 5.x tools, run ppr with the option justflatten=true, and then run lca2xnf -g on the resulting xnf file in order to convert the hard macro to representative gates. Note that this is not a complete run of ppr, producing an unrouted but flat version of the design. If you are using the new tools, hard macros are no longer supported.

If this error should occur during a timing simulation, be sure you run a functional simulation first. This error may occur if a timing simulation is run without ever running a functional simulation.
