测试覆盖率不够,用functional pattern做为补充。

run_testpoint_analysis [ -max_test_points <number>] 最多可写入的测试点数,默认为1000
[ -num_observe_points _per_cell <number>] 与扫描单元或PO异或的观察点数,默认8
[ -test _point_file <file_name>]
[ -replace]
[ -class <sub-class>] 默认分析所有未检测到的故障;可以选择特定的故障子类别,可同时选择多个子类别;
[ -dont_touch <instance>] 避免放置测试点

系统时钟启动:set_delay -allow_multiple_common_clocks
-common_launch_capture_clock选项在DRC之前发出
set_delay -disturbed(默认为开启)
