Projects / JHDL


JHDL is a set of FPGA CAD tools which allows the user to design the structure and layout of a circuit, debug the circuit in simulation, netlist, and interface with backend tools for synthesis, etc. It is an exploratory attempt to identify the key features and functionality of good FPGA tools.
