PERIOD Constraints

PERIOD Path with Phase

This is similar to the PERIOD constraint (without PHASE). The difference for this path is the source and destination clock. The destination clock defines which PERIOD constraint the path uses. Because the destination clock is the rclk_90, this path is in the TS_rclk90_dcm PERIOD and not the TS_rclk PERIOD constraint.

Notice the Requirement is now 2.5 ns and not 10 ns. This is the amount of time between the source clock (rising at 0ns) and the destination clock (rising at 2.5 ns).

Because the slack is negative, this path fails the constraint. In the Hierarchical Report

Browser, this failing path is displayed in red.

Example:

----------------------------------------------------------------------

Slack:		-2.871ns (requirement - (data path - clock skew
+ uncertainty))
Source:		rd_addr[1] (FF)
Destination:		ffl_reg (FF)
Requirement:		2.500ns
Data Path Delay:		5.224ns (Levels of Logic = 2)
Clock Skew:	-0.147ns
Source Clock:		rclk rising at 0.000ns
Destination Clock:		rclk_90 rising at 2.500ns
Clock Uncertainty:		0.000ns

Data Path: rd_addr[1] to ffl_reg
