■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...
