RC(RTL Compiler)怎样设置bc_wc时序分析

看起来不支持这个功能。
dc::set_operating_conditions
-analysis_type string
                            The only accepted value is single. This indicated that only one
                            operating condition is to be used.
-min_library string
                            Specifies the library under which the the operating condition is
                            present for hold analysis. Hold analysis is not supported by RTL
　　　　　　　　　   Compiler, but the value is written out by write_sdc.
另外，rc_ta.pdf里只有multi-mode Timing analysis，却只字未提multi-corner。
