Autoroute GND Return Vias!
Autoroute your hi-speed signals with GND Return Vias. Reduce via inductance for enhanced performance.
The new MakeDO Return Via feature transparently adds Return Via routing functionality to the PCB Router - SPECCTRA - without affecting your current design flow.
Signal Via plus GND Via = Return Via!
Pair any two existing thru, blind or buried via padstacks, assign one via as Signal and the other as GND.
