◆ chainNarrowingOffset()

long long int PNS::MEANDER_PLACER_BASE::chainNarrowingOffset ( ) const
protectedinherited

Return the length offset to subtract when converting a user-facing total signal length target into a meander-only doMove target.

The offset combines the chain-extras aggregate (other nets in the same chain) with any unmeasured stub on the actively-tuned net that lives outside the PNS-measured baseline.

Single-ended and skew tuning both rely on this so the meander does not over-correct by the chain budget already absorbed by sibling nets.
