Switch Block Models

Why is the track group segregation model easier to analyse?
  1. diagram shows repeated layout tiles
    • length 4 wires
    • only track group shown
    • i.e., one-fourth of all tracks
  2. tracks only connect within their group
    • other groups are in separate domains
    • model keeps nets within one domain or group
    • diversity possible within group, i.e. jumps from track-to-track
  3. only two types of switch blocks
    • fe at endpoints
    • fm at midpoints
  4. four turn types at endpoints
  5. one turn type at midpoints
