Anyone know why a DRC is generated when the entire
net length is correct?
The net length is supposed to be between 2000 and 2500 mils.
Probing the net gives --->Total Etch Length: 2280.31 MIL.
Very good.
When the DRC is probed, only a portion of the net is reported.
Actual value: 1032.65 MIL
Very Bad.
What up with that?
I did check the box for in the user setup for pre 11.x checking.
Thanks for the help.
