Timing - Creating Relative Propagation Delay
Creating Match Groups in CCS is as easy as ... 1 2 3.
1. Create Match Group
2. Add PinPairs to the Match Group
3. Define the Match Group Timing type - Simple Match, Match with Target, Relative Timing.
The VISUEYES parametric display shows you the timing relations as your timing constraints create them. You see the timing as you make the timing.
Correct by Design - first time, every time.
CCS will automatically setup your Match Group with the correct Delta value for each type of timing.
You can change and adjust the timing type and Delta at any time.
Delta = 0.
The Match Range is twice the Tolerance.
Pin Pairs can be in multiple Match Groups.
Selecting a Pin Pair in CCS that is in multiple Match Groups will automatically load all the Match Groups for that Pin Pair.
You can toggle through all the Match Group in the VISUEYES Rel Prop Display.
VISUEYES displays the timing to verify for you that your constraints will produce the timing Design Intent you want.
