■定义的generated_clock约束会再SpyGlass分析中生效。 ■若use_inferred_clocks参数设置为yes,derived clock信息会以generated_clock约束的形式生成在generated_clocks.sgdc和cdc_setup_generated_clock.sgdc文件中。 Verifying SpyGlass CDC Setup 在Creating SpyGlass CDC Setup之后,跑cdc_setup_checkgoal来更正和完备设置 ...
Identify clock candidates • Reset_info01: Identify reset candidates • Parameter ignore_latches: Ignores clocks driving only the latch enable pins Running CDC_Setup template will create an inferred clock constraints file called autoclocks.sgdc and an inferred resets constraint file called autoreset...
If you already know the clocks and resets specify them If you have a Synopsys Design Constraint file, use the sdc2sgdc utility to extract the clocks, resets and case analysis settings Atrenta Confidential © 2013 ...
