OrCAD Capture 7.0: design rule check gives warning message:[DRC0014] forBUFT components

Problem Title:
OrCAD Capture 7.0: design rule check gives warning message:[DRC0014]
forBUFT components



Problem Description:
When using three-state buffers (i.e. BUFT8) in an Orcad Capture design, it may
give the following error when running a Design rule check from Orcad.

[DRC0014] Type of pin above does not match the pin type of corresponding
port below U...(which repeated for every single output pin of the macro.



Solution 1:

This message comes because the symbol output pins of the BUFT8 have been labeled
 type "3 state" and the output pins of the underlying schematic are of type "out
put"

This will not cause a problem when implementing a design because the net type do
es not get passed on to the xnf file.

This apears to be an oversight in the creation of the libraries and has been bro
ught to the attention of Orcad.

To prevent the message from appearing you can descend into the BUFT8 or other BU
FT component and change the output types to 3 state.
NOTE: To descend down the hierarchy you may need to change the component type to
 not primitive.

Other elements with with mislabeled ports are: BUFE, BUFE4, BUFE8, BUFE16, BUFT4
, BUFT8, BUFT16, OBUFE, OBUFE4, OBUFE8, OBUFE16, OBUFT4, OBUFT8, and OBUFT16.
