从pt导出sdf文件时候报了很多一样的warning,我用的命令如下:
write_sdf -version 2.1 mult16.sdf
报的很多一样的warning如下:
Warning: The sum of the setup and hold values in the cell 'osc_reg[1]' for the arc between pins 'CK' and 'D' is negative, which is not allowed. To make it positive, the minimum hold value has been adjusted from -0.061186 to -0.038948.
这个怎么处理啊,是不管还是我encounter做错了?
多谢指点

没关系,就这样了
谢谢哈,我之前没人回复我就跳过了这个问题直接导出了,不过打开sdf里面interconnect里面的全部都是零,我是通过calibre提的spef,主要是库文件没电容表和线载模型,但是我通过encounter导出的就不是0,不过我记得没有模型encounter会采用自己的算法,不知道我的sdf文件是不是哪出错了
为什么没关系呢?
