如何检查removal time和recovery time

522526tl

DC里有一个 removal time 和 一个 recovery time 请问是不是要在sdc文件里设置一下，才能在report_timing的报告中看到结果呢？
Startpoint: UFF5(falling edge-triggered flip-flop clocked by CLKP)
Endpoint: UFF6 (recovery check against rising-edge clock CLKP)
Path Group: **async_default**
Path Type: max
Point Incr Path
---------------------------------------------------------------
clock CLKP (fall edge) 6.00 6.00
clock source latency 0.00 6.00
CLKP (in) 0.00 6.00 f

... ...
UFF6/CK (DFCN ) 0.00 12.19 r
clock uncertainty -0.30 11.89
library recovery time 0.09 11.98
data required time 11.98


请问如何就能在timing的报告中出现这个 命令是什么 多谢啦
