    Autorouting vs Manual routing

    Hi all, I think for some extent critical signals can also be routed(I'm talking in the case of specctra).The secret behind this is that we should give command to specctra to strictly follow the constraints.Of course we have to manually edit the net but this will take less time when considered...
