Hello Burhan num mina llah,
Thank you for sharing important notes regarding co-simulation of C++ with Optisystem. It is worth mentioning here that be it Matlab code now or C++ code , we can easily interface both with Optisystem now. It has made Optisystem very flexible now. If i remember rightly, burhan num you had to convert Simulink block into Matlab asnd you were able to convert it into C++ only but now your problrm will be solved as you rightly said , you can co-simulate it with Optisystem.
Regards
