Manta Tool

Manta is a tool for moving data between a host machine and a FPGA over UART or Ethernet. It's primarily intended for debugging and rapid prototyping of FPGA designs, but it's robust enough to be used as a simple, reliable transport layer.

Manta works by generating a number of cores that are instantiated in the FPGA design. These allow for a variety of functions, such as reading and writing to registers and memory, or capturing data with a logic analyzer. These cores are operated by the connected host machine through either the Manta CLI, or a simple Python API.

Manta is written in Amaranth HDL, and the generated designs may be used natively in other Amaranth designs, or exported to vendor-agnostic Verilog-2001. All dependencies are cross-platform, so Manta can be used on any machine that has at least Python 3.8 or newer installed.
