Problem Title:
OrCAD Capture 7.0: design rule check gives warning message:[DRC0014] for BUFT 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 "output"
This will not cause a problem when implementing a design because the net type does not get passed on
to the xnf file.
This apears to be an oversight in the creation of the libraries and has been brought to the attentio
n of Orcad.
To prevent the message from appearing you can descend into the BUFT8 or other BUFT component and cha
nge 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, OBU
FE, OBUFE4, OBUFE8, OBUFE16, OBUFT4, OBUFT8, and OBUFT16.
