Hey Dave.. Howz things.. I believe it is getting confused with the AD:AR All Drivers/All Receivers in the pin pair field. The delay rule could be used to DRC total etch length in 11.X only when you had the pin pair field blank. DELAY_RULE = ::2000:2500 This would convert to the following rule during uprev: PROPAGATION_DELAY = L:S:2000:2500 With the PRE_12.0_DELAY_RULE env variable that you have set it will check the rule the total length of the net only when you have Longest and Shortest in the Pin Pair field.

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.
