Hi,
My system simulation is in LTSpice, I want to use the THS4551, but there is only a TINA spice model. I followed these instructions: https://training.ti.com/how-convert-tina-ti-model-generic-spice-model
However there is no longer an option to "save as" .CIR. So, I copied the text within TINA and pasted in notepad++ then tried to "save as" .CIR. But the simulation isn't working - running really slow and not resolving, waveforms do not look correct, etc.
