CST - How to Replicate a Battery Management System (BMS) in Software for EMI/EMC Simulation?

Hi everyone,
I have a question related to EMI/EMC simulation for a Battery Management System (BMS).

For most components, we usually use SPICE models (for MOSFETs and power devices), S-parameters (for RF or passive components), or IBIS (for digital ICs).

But I wanted to understand — how can we replicate or simulate a complete BMS in software for EMI/EMC analysis before hardware testing?

Are there any reference workflows or example projects that demonstrate this type of EMI/EMC setup?

Any references or guidance would be really helpful.
