Routing Delay
Compression (2)
•Delay
values are grouped into delay groups, each with a notation: G=(S1,P1,S2,P2,X,Y)
–S1,P1
= source slice & pin
–S2,P2
= target slice & pin
–X,Y = relative location of target pin to source pin
•An
intersect point is identified for capturing column and row vectors of delay values to
describe
delays in the whole group
