Filter Design HDL Coder

Generate HDL code for fixed-point filters

Filter Design HDL Coder™ generates synthesizable, portable VHDL® and Verilog® code for implementing fixed-point filters designed with MATLAB® on FPGAs or ASICs. It automatically creates VHDL and Verilog test benches for simulating, testing, and verifying the generated code.
