set_case_analysis 0 UCORE/UMUX2/CLK_SEL[2] 图1 2. 中断时序弧 如果单元内的某条路径无法发生,可以通过set_disable_timing中断该时序弧,工具对所有经过该时序弧的路径都不进行时序检查。 例如:比较常用的,时钟连接到多路复用器的选择端,而多路复用器的输出是数据路径的一部分,如图2所示。需要中断多路复用器...
Set case analysis(设置案例分析)命令通常通过对逻辑如配置寄存器设置常数值来描述功能模块,设置对象可为端口,线net,层级引脚或子模块输入引脚,常数值通过约束的逻辑单元传输,从而关闭该单元的任何时序分析,功能和设置set false path类似。约束可以在SDC、XDC文件中使用。 使用set case analysis可以减少分析的空间,运行时...
Reason why, I’m looking for a “set_case_analysis” command or equivalent. Another option would be to use set false path command from node A to node B with specific launch clock and latch clock. Is it possible ? Thanks for your help. Translate Tags: SDC 0 Kudos R...
The ArcGIS Enterprise Software Development Kit (SDK) allows developers to extend the functionality of ArcGIS Server map services published via ArcGIS Pro.
Due to unsupported set_case_analysis command, I try to use set_disable_timing command to do this. Unfortunately, I don't know that the node A is on the dataa, datab, datac, datad, datae, or dataf before synthesis.And I had tried to set_false_path comman...

If there are still failing paths in the design between unrelated clock domains, you can start add the new clock domains as necessary. In this case, a large number of the clocks are not in the set_clock_groups command, since they are either cut in the .sdc file for the IP core (such...

Avrum gave you some fantastic detail in his response and he is 100% correct. I will add a tiny bit to this. We are not really stuck w/ SDC technically speaking. For example the datapath_only option to set_max_delay is after all an extension that we implemented that diverges from ...
