Placement for digital VLSI design

This is a utility used to perform placement of digital VLSI designs. It is based on some code from the early 90s and it is one of the building blocks of the open source qflow digital design flow.

Open-Source Digital Synthesis Flow

This is a complete tool chain for synthesizing digital circuits starting from verilog source and ending in physical layout for a specific target fabrication process. In the world of commercial electronics, digital synthesis with a target application of a chip design is usually bundled into large EDA software systems. As commercial electronics designers need to maintain cutting-edge performance, these commercial toolchains get more and more expensive, and have largely priced themselves out of all but the established integrated circuit manufacturers. This leaves an unfortunate gap where startup companies and small businesses cannot afford to do any sort of integrated circuit design. Qflow tries to fill this gap.
