After simulating signal-via bypassing (Simulate PI > Analyze Signal-Via Bypassing), I see the following lines in the resulting report (BW.log):
Processing VRMs for transmission plane with layers "SIGNAL_4"-"SIGNAL_5" (nets "GNDA2"-"+0.975VxxxA2")
Cannot find any VRM between nets "GNDA2" and "+0.975VxxxA2"
Failed to create VRM model; VRM omitted
On the schematic, "+0.975VxxxA2" is connected to "+0.975VA2" via inductance (LR139).
"+0.975VA2" is assigned to VRM model.
When assigning it to VRM model (Models > Assign Power Integrity Models), I have verified in Supply-Net Inductors tab that LR139 is present in the list (and not removed).
So, what else should I do to see the following line in BW.log ?
VRMs for transmission plane with layers "SIGNAL_4"-"SIGNAL_5" (nets "GNDA2"-"+0.975VxxxA2") were added successfully
