SpyGlass,这是一个很强大的RTL验证级工具。它不仅仅能检查sdc的错误,还能做以下各种检查:LowPower,DFT,CDC(Cross Domain Check)。其中用得最多的就是... analysis值也设好。一些不方便处理的模块,如IO mux,可以用black box处理assume_path。然后分析每一条报出来的Error,或者添加约束,或者waive。 公司招聘 各大...
VC SpyGlass CDC offers low-noise clock domain crossing verification with comprehensive structural and functional analysis for reliable signoff.
Synopsys VC SpyGlass 数据手册说明书 DATASHEET synopsys.com Overview Among the many verification challenges confronting system-on-chip (SoC) designers today, clock domain crossings (CDC) ranks near the top in difficulty. Today’s SoCs have dozens, sometimes even hundreds, of asynchronous clock domains...
Synopsys SpyGlass CDC provides comprehensive, low-noise clock domain crossing verification for design-and-debug CDC issues.
The SpyGlass CDC Methodology Flow 各个阶段介绍: Creating SpyGlass CDC Setup.Goal:cdc_setup;指定constraints(SGDC file),parameters 及其他指定用于该project的定义来精准运行SpyGlass CDC检查。可以使用‘sdc2sgdc’ 命令来将 block-level SDC 转化成相应的SGDC 约束文件。运行‘cdc_setup_check’ goal能够生成constra...
