Hello !
I am working on cosimulation of a specific project between Matlab and ModelSim as HDL simulator. Matlab script, and simulink model communicate using from workspace blocks.
Inside Matlab script I use the following command to lunch ModelSim on batch mode:
tclcmd = { ...
'vsimulink top_tsr -t 1ns -voptargs=+acc ;', ...
'add wave top_tsr/*;', ...
};
vsim('tclstart',tclcmd,'runmode','Batch')
And the following cmd to lunch simulink cosimulation:
Sim_out = sim('TSR_CoSim');
What I want to do now is to implement the same module using cosimulation with Vivado instead of ModelSim.
I have generated the .slx model that contains vivado block.
i just need to call vivado from matlab to make it ready for Cosimulation.
Thank you

The Vivado Simulator cosimulation process is different than that for ModelSim. For Vivado, a shared library containing the Vivado simulation kernel is created that is run in the context of the Simulink model--there is no other Vivado process to launch during the cosimulation.
Running the "Getting Started" example will probably best help you understand the process: https://www.mathworks.com/help/hdlverifier/ug/get-started-simulink-cosimulation-hdl.html
The example covers ModelSim, Xcelium, and Vivado Simulator so be sure to follow the instructions for Vivado Simulator.
