Hi all,
I'm setting a region in the BGA area for 4 mils spacing line/line. My 90 ohm pair came out to be 3.7mil spacing so it violates this rule. I know I can lower the constraints with in the region to meet this demand, but I prefer to keep the spec at 4 mils for rest of the traces.
I have checked the setting in Setup>constraints>modes>electrical options>Differential Pair Constraints which helps me maintain the line/space, but it still shows the DRC for line/line spacing for violating the 4 mil space.
Is there a way to avoid this DRC within this region without editing the region shape or adding another region?
Also my default constraints are set to 5 mil spacing it does not DRC the diffpair gap. it's only for the region area.
Please let me know if anyone has suggestions.
