Interfacing to Hardware from M-Code - Interfacing to Hardware from M-Code - 2026.1 English - UG1483

After compiling a model for hardware co-simulation, you can use the generated bitstream in a model-based Simulink flow. Alternatively, you can use the bitstream in M-code executed in MATLAB. The general sequence of operations to access a bitstream in hardware is as follows:

1. Configure the hardware co-simulation interface.
   Note: The hardware co-simulation configuration is persistent and is saved in the hwc file. You do not need to run this step if the co-simulation interface did not change.
2. Create a M-Hwcosim instance for a particular design.
3. Open the M-Hwcosim interface.
4. Repeatedly run the following sub-steps until the simulation ends.
5. Write simulation data to input ports.
6. Read simulation data from output ports.
7. Advance the design clock by one cycle.
8. Close the M-Hwcosim interface.
9. Release the M-Hwcosim instance.
