HDL Verifier


HDL Verifier

Verify VHDL and Verilog using HDL simulators and FPGA-in-the-loop test benches


HDL Verifier™ automatically generates test benches for Verilog® and VHDL® design verification. You can use MATLAB® or Simulink® to directly stimulate your design and then analyze its response using HDL cosimulation or FPGA-in-the-loop with Xilinx®, Intel®, and Microsemi® FPGA boards. This approach eliminates the need to author standalone Verilog or VHDL test benches.

HDL Verifier also generates components that reuse MATLAB and Simulink models natively in simulators from Cadence®, Mentor Graphics®, and Synopsys®. These components can be used as verification checker models or as stimuli in more complex test-bench environments such as those that use the Universal Verification Methodology (UVM).


HDL Cosimulation

Verify that HDL code implementation matches MATLAB algorithms and Simulink models.

Debug and Verify System Designs

Use system test benches and golden reference models in MATLAB and Simulink to verify that Verilog or VHDL code meets system specifications. Verify designs using MATLAB or Simulink with Cadence® Incisive® and Xcelium™ simulators, Mentor Graphics® ModelSim® and Questa® simulators, or the Xilinx® Vivado® simulator.

Integrate Existing HDL Code

Incorporate legacy or third-party HDL code into MATLAB algorithms or Simulink models for system-level simulation. Use the Cosimulation Wizard to automatically import Verilog or VHDL code and connect to Mentor Graphics or Cadence HDL simulators.

SystemVerilog DPI Generation

Export MATLAB algorithms or Simulink models to ASIC or FPGA verification environments including Synopsys VCS®, Cadence Incisive or Xcelium, and Mentor Graphics ModelSim or Questa.

Component Export

Generate SystemVerilog DPI components from MATLAB functions or Simulink subsystems as behavioral models for use in functional verification environments.

UVM Support

Generate verification components from MATLAB functions or Simulink models and incorporate them into test benches as scoreboards or sequence items using the Universal Verification Methodology (UVM).

Hardware-Based Verification

Debug and verify algorithms on FPGA boards connected to MATLAB or Simulink test environments.

FPGA-in-the-Loop Testing

Use system test benches running in MATLAB or Simulink to test HDL implementations executing on FPGA boards. Connect your host computer automatically to Xilinx, Intel®, and Microsemi® FPGA boards over Ethernet, JTAG, or PCI Express®.
