[PCB_FORUM] ICT

Hello group,
We are using ICT more and more and would like to find out what the most efficient way to do this.
Is it better to route the board then run ICT ?
Or place components, fanout all signals to bottom side, run ICT then route the board?
Is it easier in Specctra or Allegro?

Is there a way in Allegro to give all testpoints a temporary place holder to ensure a TP location after routing.

Currently, we are routing the board, Run ICT to replace vias as TPs where it can. Then run a pass to add TP "pads" with no drill on bottom side. Trying to allow on traces where it can. Then run again allowing stringers to these pads.

Any comments would be appreciated.
