当设置好了在PADS Router自动扇出所需的过孔,线宽等参数后,发现自动扇出时出错,如下图所示,“... are disabled for routing. To correct the problem, use the Design Rules dialog box in PADS Layout or the Routing tab of the Design (or Net) Properties dialog box in PADS Router. ”
可能的原因之一是,在PADS Router中Design Properties设置对话框下的Routing页,Allow Autorouting选项被误非选了,正确应该是允许自动布线的,这样才能使用自动扇出Fanout功能,如下图所示,否则只能设置好栅格后手动扇出。
