Presentation
Noise Fixup: Finding and Fixing Noise Problems ( Chop and Swap )
DescriptionChop and Swap methodology was architected for noise mitigation that saved
multiple designers weeks of manual chip integration work in a project.
When a noise event happens, the closer the aggressor and victim wires are, the
more noise coupling occurs, causing NIOT (Noise Impact on Timing) or NIOF
(Noise Impact on Function) fails. Chop and Swap methodology identifies long
parallel lines between aggressor and victim wires, then chops the wire into pieces
and moves them further away from each other. Chop and Swap carefully
optimizes the location of the wire so that it not only reduces NIOF fails by 10x, but
also improves timing most of the time. Chop and Swap was used to solve 10s of
thousands of NIOF fails overnight in our latest project. Prior to automation these
fails were addressed manually, requiring several integrators working several
weeks.
This work provides tremendous productivity and turn-around-time (TAT) boost in a
modern complex chip-level design.
