HDL Coder


HDL Coder

Generate VHDL and Verilog code for FPGA and ASIC designs

HDL Coder generates portable, synthesizable Verilog® and VHDL® code from MATLAB® functions, Simulink® models, and Stateflow® charts. The generated HDL code can be used for FPGA programming or ASIC prototyping and design.

HDL Coder provides a workflow advisor that automates the programming of Xilinx®, Microsemi®, and Intel® FPGAs. You can control HDL architecture and implementation, highlight critical paths, and generate hardware resource utilization estimates. HDL Coder provides traceability between your Simulink model and the generated Verilog and VHDL code, enabling code verification for high-integrity applications adhering to DO-254 and other standards.

HDL Code Generation

Develop and verify hardware designs at a high-level of abstraction and automatically generate synthesizable RTL code to target FPGA, ASIC, or SoC devices.

High-Level Hardware Design

Design your subsystem by choosing from over 300 HDL-ready Simulink blocks, MATLAB functions, and Stateflow charts. Simulate the hardware behavior of your design, explore alternative architectures, and generate synthesizable VHDL or Verilog.

Vendor-Independent Targeting

Generate synthesizable RTL for use in a range of implementation workflows and FPGA, ASIC, and SoC devices. Reuse the same models for prototype and production code generation.

Generating efficient vendor-independent synthesizable RTL that can be deployed on any FPGA, ASIC, or SoC device.

Readable, Traceable HDL Code

Comply with functional safety standards such as DO-254, ISO 26262, and IEC 61508 by maintaining traceability between your requirements, model, and HDL. The generated HDL complies with industry-standard rules and is readable for code reviews.
