Project Description

By simulator + Tcl + C language, let's verify ASIC and FPGA effectively!

(simulator <= DPI-C => C++, simulator <= named pipes => C++ are under development, too.)

NOODLYBOX is a mimic processor for verification.

It can manipulate FPGA model which is connected to microcomputer's local bus.


  1. A microcomputer and FPGA are mounted on a printed circuit board.
  2. A microcomputer and the connection form between FPGA are SRAM interface.
  3. FPGA is modeled by VHDL or Verilog.
  4. ModelSim, ISE Simulator, or Icarus Verilog are installed.

When all the conditions mentioned above are met, NOODLBOX can act as the substitute of the microcomputer on an HDL simulator.
