Custom Qspice symbol library for c++ blocks


Is there any available documentation on how to link custom symbols to schematics, particularly when they are based on custom C++ code?

I am in the process of creating a QSPICE symbol library, primarily comprised of C++ code blocks. My vision for this project is to develop something akin to the MATLAB/Simulink structure, incorporating mathematical operations (e.g., ADD, MULTIPLY), discrete controls (e.g., PID, LPF, FIR, IIR), and so forth.
However, I find myself struggling to link a custom symbol to its corresponding schematic and integrate it into the main project schematic. Any documentation, advice, or tips on how to accomplish this would be immensely helpful for QSPICE beginners like myself.

Hi Nikola, it has exist
