o Transition Time (Slew):
o
Set a max_transition constraint. tool will
automatically insert buffers as needed to ensure no segment of the clock tree
exceeds this targeted trans limit.
o
Skew:
o
Set a target skew limit. tool will use this as a
target for balancing.
o
Clock mesh or multi tap CTS instead of a conventional
tree, or building a well-balanced H-tree, can control skew.
o
Using NDRs with wider wires reduces RC
variation, which helps minimize skew.
