VCS默认的路径延时(module path delay),sdf文件反标的互联延迟(INTERCONNECT delay)为惯性延迟。而原语 ...

老实说,你看这种翻译文章还不如直接看guide,这段话译自guide中:
You can apply transport delays on all module path delays and all SDF INTERCONNECT delays back-annotated to a net from an SDF file.
和
Gates, switches, MIPDs, and continuous assignments only have inertial delays, which are the default type of delay for module path delays and INTERCONNECT delays back-annotated from an SDF file to a net.
对VCS而言,这两种delay可以视为模式或者属性。系统默认对来自SDF的所有延时(module path delay and wire delay)均赋inertial delay属性,但是你可以手工更改为transport delay。例外的是门级(Gates, switches, MIPDs, and continuous assignments)均无法赋transport delay。
The difference betwwen transport delay and inertial delay is whether a pulse with narrower width can path through the module or wire. |
