在PT里report_timing -pba_mode 的option有path和exhaustive两个,解释如下:
-pba_mode none | path | exhaustive
Controls path-based analysis with the following modes:
o none (the default) - Path-based analysis is not applied.
o path - Path-based analysis is applied to paths after they have
been gathered.
o exhaustive - An exhaustive path-based analysis path search
algorithm is applied to determine the worst path-based analy-
sis path set in the design. If you use exhaustive, you cannot
use the -start_end_pair or path_collection options.
这个path和exhaustive有什么区别?难道不都是用真实的arc进行计算delay吗?
