o We can run IR aware full flow
o
IR aware placement : Spread high power
density hotspots to reduce IR drop. Tools settings using setPlaceMode. This is
useful even during routing as during optimization tool adds buf/inv and updates
placement increamentally.
o
CCopt/SkewClock: skew the clock to
minimize peak current
o
Reinforce_pg: Auto RPG: Loacl PG
stripe/via addition in hotspot area. (separate utility from cadence. Needs
voltus IR setup as input.
o
Fill: Maximize PG hookup at signoff
stage.
o In
general routers are now performs rudimentary current density estimation on
wires and handles IR/RM.
