INV的layout
我用的是CSMC500nm的工艺
这是错误截图,可能看不清,说的是:Error: Valid Vias not present in interconnect section in the LEFDefaultRouteSpec constraintgroup.Add the Vaild Vias section in the interconnect section in the LEFDefaultRouteSpec constraintgroup or change the constraint group from File:GEneral Options section and try again.
INFO:Verifying Technology Data ...
Error: The A1 layer does not have a minimum winth.
Error: The A1 layer does not have a minimum spacing value defined.
Error: The routing direction for A1 is specified but no pitch value is present in the technology file.
A2 和 T3也是一样的错误,但我看了tf文件,是有定义的啊,详细内容我写了个文档,请大神指导一下,不胜感激!!!
