USE EDGE
Use a edge clock resource to route the specified net:
CLOCK_TO_OUT
Specifies a maximum allowable output delay relative to a clock.
Here are two preferences using both the CLKPORT and CLKNET keywords showing the corresponding scope of
TRACE reporting.
The CLKNET will stop tracing the path before the PLL, so you will not get PLL compensation timing numbers.
The above preference will yield the following clock path:
If CLKPORT is used, the trace is complete back to the clock port resource and provides PLL compensation timing
numbers.
The above preference will yield the following clock path:
INPUT_SETUP
Specifies an setup time requirement for input ports relative to a clock net.
PLL_PHASE_BACK
This preference is used with INPUT_SETUP when a user needs a trace calculation based on the previous clock
edge.
This preference is useful when setting the PLL output phase adjustment. Since there is no negative phase adjust-
ment provided, the PLL_PHASE_BACK preference works as if negative phase adjustment is available.
