I read a lot about IBIS, what I understood is that they basically model the input output voltage, current data based on actual performance instead of describing through equations like in SPICE. Please correct me if I am wrong. However, I cannot for the life of me understand where they are used. It is said to be supported by 'virtually any simulation software', however it isn't on LTspice or TINA. Then I come across posts like these (https://en-support.renesas.com/knowledgeBase/4967225#:~:text=Answer%3A,the%20device%27s%20I%2FO%20pins.&text=An%20IBIS%20model%20does%20not,be%20used%20for%20SPICE%20modeling.) which say it does not work like SPICE model. So what exactly do they do? Can I connect, say, resistors around IBIS model of an op-amp in non-inverting configuration and expect to see an amplification? Or do I need to convert it to SPICE, or neither? I am very confused. Please help.
