Cosimulation with Simulink
- HDL Cosimulation
The HDL Verifier software consists of MATLAB functions, a MATLAB System object™, and a library of Simulink blocks, all of which establish communication links between the HDL simulator and MATLAB or Simulink.
- Performing Cosimulation
Next steps after you generate a function or block representing your HDL module.
- Prepare to Import HDL Code for Cosimulation
Prepare for cosimulation and choose whether to cosimulate your HDL code as a function, System object, or block.
- Import HDL Code for HDL Cosimulation Block
Generate a Simulink block to cosimulate your HDL code.
- Run a Simulink Cosimulation Session
Run your test bench or algorithm, including the cosimulation of your HDL module.
- Use HDL Parameters in Cosimulation
Use Verilog parameters or VHDL generics in cosimulation.
HDL Simulator Interaction
- Simulation Timescales
The representation of simulation time differs significantly between the HDL simulator and Simulink.
- Clock, Reset, and Enable Signals
You can create rising-edge or falling-edge clocks, resets, or clock enable signals that apply internal stimuli to your model under cosimulation.
- Simulation Speed Improvement Tips
Provides suggestions for optimizing your cosimulation performance.
- Supported Data Types
If your HDL application needs to send HDL data to a MATLAB function or a Simulink block, you may first need to convert the data to a type supported by MATLAB and the HDL Verifier software.
- Race Conditions in HDL Simulators
Describes ways to avoid race conditions in hardware cosimulations with MATLAB and Simulink software.
Recording Signal State Transitions for Post-Processing
- Add a Value Change Dump (VCD) File
A value change dump (VCD) file logs changes to variable values, such as the values of signals, in a file during a simulation session.
- Visually Compare Simulink Signals with HDL Signals
