Routing Delay
Compression (3)
1.Convert
delays into integers by a scaling factor of
0.02ns
2.Normalize
delays using delay at the intersect pt
3.2
1-D vector of delay values are collected at the intersect
4.Zeroes
in the delay vectors are eliminated
5.Duplicates
in the delay vectors are eliminated
6.Make
use of symmetry of pins: P1=X & P1 = Y, P1 = XQ & P1 = YQ
7.Record
data points explicitly when the scheme fails
8.Compression
Ratio achieved = 100x
