Mithlesh, Yes, you are correct. The I/O model_type will consist of the following V/I anf V/T tables Pullup Pulldown Gnd clamp Power clamp Riseing waveforms Falling waveforms For output only model_type, remove the ground and power clamps. For Input only model_type, remove the pullup, pulldown, rising and falling waveforms. Hope this helps. Feel free to ping me if you have any other questions.

Few pins are I/O, Output only and Input only. The output only models do not have power/ground clamp curves and Input only models have only clamp curves. i.e. if i remove particular section, i can convert a IO model to output/Input models, right? Now, do i need to separately define Output & Input only models to particular pins or I use the IO type model for them as well? ----------------- [model selector] io_type IO models [model selector] output_type Output models (or IO models ???) [model selector] Input_type Input models (or IO models???) ----------------- Highly appreciate your quick response. Thank you! Mithlesh -- ---" "----------------------------" "--.
