Introduction

This is gaofeng's edit!

The Verilog-to-Routing (VTR) project is a world-wide collaborative effort to provide a open-source framework for conducting FPGA architecture and CAD research and development. The VTR design flow takes as input a Verilog description of a digital circuit, and a description of the target FPGA architecture. It then perfoms:

• Elaboration & Synthesis (ODIN II)
• Logic Optimization & Technology Mapping (ABC)
• Packing, Placement, Routing & Timing Analysis (VPR)

to generate FPGA speed and area results. VTR also includes a set of benchmark designs known to work with the design flow.

License

Generally most code is under MIT license, with the exception of ABC which is distributed under its own (permissive) terms. Full license details can be found here.

Download

For most users of VTR (rather than active developers) you should download the latest packaged (and regression tested) version of VTR from here.

Building

On unix-like systems run make from the root directory.

For more details see here.

Documentation

VTR's full documentation is available here.

Development

This is the development trunk for the Verilog-to-Routing project. Unlike the nicely packaged releases that we create, you are working with code in a constant state of flux. You should expect that the tools are not always stable and that more work is needed to get the flow to run.

For new developers, please do the tutorial in tutorial/NewDeveloperTutorial.txt. You will be directed back here once you ramp up.

VTR development follows a classic centralized repository (svn-like) workflow. The 'master' branch is supposed to be the most current stable version of the project. Developers checkout a local copy of the code at the start of development, then do regular updates (e.g. git pull) to keep in sync with the GitHub master. When a developer has a tested, working change to put back into the trunk, he/she performs a git push operation. Unstable code should remain in the developer's local copy.

We do automated testing of the trunk using BuildBot to verify functionality and Quality of Results (QoR).

• Trunk Status
• QoR Tracking

IMPORTANT: A broken build must be fixed at top priority. You break the build if your commit breaks any of the automated regression tests.

For additional information see the developer README.
