Abstract
A method for enabling functionality in circuit designs utilizing colorless DPT M1 route placement that maintains high routing efficiency and guarantees M1 decomposability of a target pattern and the resulting circuit are disclosed. Embodiments include: determining a boundary abutting first and second cells in an IC; determining a side of a first edge pin in the first cell facing a side of a second edge pin in the second cell; determining a first vertical segment of at least a portion of the side of the first edge pin and a second vertical segment of at least a portion of the side of the second edge pin; designating an area between the first vertical segment and the boundary as a first portion of a routing zone; and designating an area between the second vertical segment and the boundary as a second portion of the routing zone.
