    Set Max line width as nominal in the constraint manager. Reply

    Good afternoon,

         Is there a way to set the maximum line width in the constraint manager as the "nominal"?  I have a power trace with a min of 10 and max of 50.  95% of the trace will be 50.  The remaining trace segments go to a test point and secondary components, which do not need to be 50.  When I start the trace it always uses the 10mil setting.

    Thank you,

    Set the Min Line width to the "normal" 50 width for the rule, set the Neck Width to 10, set the Neck Length to long enough for all the Necked Segments (16.5 and later), the length of any individual segment (16.3 and earlier). When routing, right-click>Neck Mode to get the "10" width, otherwise you will get the "50" width. Change Width should still let you have less than 50 and more than 10 without a DRC.

    Thank you Mr O,

        I have used neck mode on several occasions, but was still stuck in the Layout mode of min, nom, max.  Simple, thanks.
