TritonRoute

TritonRoute is an open-source detailed router for modern industrial designs. The router consists of several main building blocks, including pin access analysis, track assignment, initial detailed routing, search and repair, and a DRC engine. The initial development of the router is inspired by the ISPD-2018 initial detailed routing contest. However, the current framework differs and is built from scratch, aiming for an industrial-oriented scalable and flexible flow.

TritonRoute provides industry-standard LEF/DEF interface with support of ISPD-2018 and ISPD-2019 contest-compatible route guide format.
