You can use the Generate Testbench feature of HDL Coder to generate an HDL testbench that takes the simulation input and output and constructs an HDL testbench. The HDL code and testbench can run in any HDL simulator of your choice (there are options to generate the required scripts to run the code).
You can also verify the HDL code using a DPIC-C testbench, HDL cosimulation or FPGA-in-the-Loop. These options are described for a Simulink model in this page.
