We set design rules to traces to meet required impedance. Those rules (clearance, width, ..) cannot be met near a component.

One solution is to query those out and set other (lower) rules (which does not significantly impact on impedance).

I have 2 rooms: one over USBHub named NearUsbHub and other over USBBridge named NearUsbBridge, where query seems works OK,

InAnyDifferentialPair And (InComponent('U*') Or WithinRoom('NearUsbHub') Or WithinRoom('NearUsbBridge'))

but InComponent('U*') select only pads - that are connected to differential pair nets.

Can I query traces on component area without setting new room on each matched component?
