我正在「拾陆楼」和朋友们讨论有趣的话题,你⼀起来吧?
NRDB-2276:Net xxxx has top and bottom routing layer as M6 M2, But nets have top and bottom preferred routing layer as M11 M8 and the preferred routing layer effort is medium or high. Top and bottom preferred routing layers should be within top and bottom layer range
NanoRouteMode中设置绕线层次2-6,但是被动到的special net有8-11的preferred route layer,这个层次可能是create_route_type+set_ccopt_property -net_type 定义的。
二者绕线层次范围有冲突,导致在调整过这条net后再绕线就会提示失败。
解决办法可以是:
selectNet xx
setNanoRouteMode -routeTopRoutingLayer M11 -routeBottomRoutingLayer M8
globalDetailRoute -select
然后再下route_design 等route命令去绕别的net。
