set_svf,设置svf文件路径和名称; set_verification_priority,可以将某些design(reference)的verify优先级调高,从而在formal verification的verify阶段,更容易比过(可以用来解决abort的问题); set_multibit_options,设置多比特DFF的选择标准,比如设置为“timing_driven”就是时序驱动的; set_clock_gating_style,来设置ICG...

不需要从DC输出SDF,因为那个根本不准,而且它也无法保证没有hold违反 Q1.3 如何让DC自动插入clock gating 在脚本中加入 set power_cg_always_enable_registers true set_max_leakage_power 0.0 set_max_dynamic_power 0.0 set_clock_gating_style (指定ICG) insert_clock_gating replace_clock_gates Q1.4 综合时要...
Controls whether thecompilecommand preserves the subdesign interface. When this variable is set totrue, it disables customization of logic external to a subdesign duringcompile, and preserves the subdesign interface. When set tofalse(the default),compilecustomizes the logic external to a subdesign b...

之前,我们应先使用命令 set_clock_gating_style 来指定要插入门控时 钟的结构。且此处勾选Gate clock 选项。 点击OK 执行Elaborate。执行结果如下图: 当控制台出现 Presto compilation completed successfully. 表示 elaborate 成功。点击create symbol view 所指向的按钮可以看该电路 ...

Step 4. Enable clock gating for low power (optional) 4(a) The following commands will try to insert clock gates for each 2 registers set_clock_gating_style -minimum_bitwidth 2 Step 5. Write formal verification setupfile (optional)
