Manta: An In-Situ Debugging Tool for Programmable Hardware

Manta is a tool for debugging FPGA designs over an interface like UART or Ethernet. It works by allowing the user to instantiate a number of debug cores in a design, and exposes a Python interface to them. This permits rapid prototyping of logic in Python, and a means of incrementally migrating it to HDL. The cores are described below.

Manta is written in Python, and generates Verilog-2001 HDL. It's cross-platform, and its only dependencies are pySerial and pyYAML.
