That was probably because TI give very accurate 'deep-dive' models for their SMPS chips. I haven't compared speeds but find the things I do come up almost immediately.</div>

<div class="">I once tried Tina-TI, and my first impression was that simulation is way slower than in LTSpice. AFAIR simulating a simple switch-mode power supply took hours. But for a fair comparison, one should simulate exactly the same circuit in both programs
(which I didn’t). Has anyone tried that?</div>
