用Encounter做APR,在sdc文件里使用set_driving_cell设置clock端口的驱动单元,但是在CTS的时候,还是报告No Driving Cell Specified!
# Analysis View: worst
********** Clock HCLK Clk-Route-Only Timing Analysis **********
Nr. of Subtrees: 1
Nr. of Sinks: 1205
Nr. of Buffer: 189
Nr. of Level (including gates) : 8
Root Rise Input Tran: 0.1(ps)

No Driving Cell Specified!
大家知道这是为啥吗?
谢谢

不清楚,没关系吧
要么就是sdc没声明对,要么就是跟clock spec file里没声明addDriverCell
