Hi Gary,
 
In order to include the package lengths in a component you need to add
them to the packages section of the schematic symbol. These values will
then appear in the Pin Delay columns.

Hey guys,
 
It has reached the point where I have to consider the package length
when matching some nets.
I am using Relative Propagation Delay in CM, and was wondering if anyone
knows how to include the package lengths?
I thought maybe the Pin Delay columns, but they are grayed out.
 
Any ideas?
 
Regards,
Gary
