Witryna1 sty 2013 · The options -logically_exclusive, -physically_exclusive, and -asynchronous are mutually exclusive. You can use only one option in a single set_clock_groups command. However you can specify relationships between clocks in multiple commands which could be different. Witryna7 lut 2024 · Logically exclusive means - Both the clocks(or clock groups) can exist (can be active) simultaneously in the design and the clocks have SI impact on each other’s …
Witryna23 gru 2024 · physically_exclusive: Means Timing paths between these clock domains are false, but only one clock can exist in the design at the same time. ETS/Tempus will filter out the SI interactions of nets/paths between these groups. ... Logically exclusive means the timing paths between these clock domains are false, but both clocks can … WitrynaCommon Multicycle Applications. Multicycle exceptions adjust the timing requirements for a register-to-register path, allowing the Fitter to optimally place and route a design. Two common multicycle applications are relaxing setup to allow a slower data transfer rate, and altering the setup to account for a phase shift. 3.6.8.4.
