Dog-leg routing is essentially the same thing as left-edge routing, but we are allowed to use more than one horizontal segment per net. Thus in the preceding example, we would break net 1 into net 1a, and net 1b. The break would occur at column 2 (the third column from the left). Net 2 has two internal pins, so it is broken into three pieces 2a ...

In this paper we present WEVIAN, a web-based placement visualizer/analyzer that enhances the design procedure by adding interactivity and offloading part of the workload to a third-party server....

Basic Left Edge Algorithm • Simplest channel routing algorithm. • AiAssumptions: – Only two‐terminal nets. – No vertical constraints. – HV two‐layer model. 23 – Doglegs are not allowed. • Basic Steps: – Sort the nets according to the x‐coordinate of the leftmost terminal of the net.

The Left Edge Algorithm is a well-known Computer-Aided Design algorithm for wiring together terminals at the top and bottom of a rectangular region known as a channel. Terminals are placed at the top and bottom of columns in the channel. Connections are made using two layers of wiring.

Constrained Left-Edge Algorithm 1. Construct VCG 2. Sort nets on leftmost end position 3. Start next lowest track 4. Select net with lowest left position 5. If net has no decendents in VCG: Place on current track update end position on current track delete net from list and VCG 6. While there are nets which start after last position used
