Switch Block Midpoints


Consider two switch blocks, both
with same (disjoint) endpoint pattern:
  1. midpoint switch blocks with no diversity
    • same midpoint pattern everywhere
    • track t connects to track t
    • different global routes reach same track

  2. midpoint switch blocks with diversity
    • same midpoint pattern everywhere
    • track t connects to track t+1
    • different global routes reach different track
    • example: reaches 3 different tracks
    • note: can also use different midpoint pattern along length of wire (see next slide)
