TritonRoute-WXL, which is built on the open source detailed router TritonRoute, is an open source router for modern industrial designs. The router consists of several main building blocks, including pin access analysis, global routing, track assignment, detailed routing, and a DRC engine. TritonRoute-WXL was developed by graduate students Lutong Wang and Bangqi Xu at UC San Diego in La Jolla, California.
TritonRoute-WXL provides industry standard LEF/DEF interface with support of ISPD-2018 and ISPD-2019 contest-compatible route guide format. In addition, it provides a global-detailed routing interface that is compatibale with existing contest-based interface.
This version of TritonRoute makes minor modifications to work with the ACT tools for asynchronous design. Apart from minor fixes to warnings, the main differences are (i) changed the default options used by the detailed router, and (ii) the LEF/DEF libraries are assumed to be installed in ACT_HOME, so they have been removed from the build process.
TritonRoute-WXL is tested in 64-bit CentOS 6/7 environments with the following prerequisites:
- A compatible C++ compiler supporting C++17 (GCC 7 and above)
- Boost >= 1.68.0
- OpenMP >= 4.5
- Bison >= 3.0.4
- zlib >= 1.2.7
- CMake >= 3.1
- LEF/DEF libraries from Si2 installed in $ACT_HOME
To install this version of TritonRoute-WXL, make sure that the environment variable ACT_HOME is set to the install directory for the ACT tools. Also, make sure that the LEF/DEF libraries are also installed there. After this:
$ git clone https://github.com/asyncvlsi/TritonRoute-WXL.git
$ cd TritonRoute
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=$ACT_HOME ../
$ make
$ make install
To run TritonRoute-WXL for detailed routing:
$ ./TritonRoute -lef <LEF_FILE> -def <DEF_FILE> -guide <GUIDE_FILE> -output <OUTPUT_DEF>
To run TritonRoute-WXL for global-detailed routing:
$ ./TritonRoute -lef <LEF_FILE> -def <DEF_FILE> -output <OUTPUT_DEF>
- ISPD-2018 and ISPD-2019 Initial Detailed Routing Contests
