您好,这个方法我也尝试了:
setNanoRouteMode -routeBottomRoutingLayer 2
但是会出现error:
Invalid option value -routeBottomRoutingLayer 2. It is inconflict with already existing routed wires on layer 1.
The option must specify a layer equal to or below the bottom_most layer for existing routes.
但是我检查了版图,在route前并没有Li1(1) 层的出现,不知道这个问题的出现是因为什么呢?
