ltspice for gpio pin

Hi, I am working with the Deo Nano SoC. I need to drive some mosfets to get 5v 7MHZ square waves and 100KHz 27v square waves. I need to find a model one can use with LTspice to simulate a GPIO p...

(1) Find your Altera FPGA device here: https://www.altera.com/support/support-resources/download/board-layout-test/ibis/ibs-ibis_index.html and get the IBIS model(s) for the pins you are interested in.

(2) Google 'ibis to spice converter'. There are lots of free tools available that can convert IBIS models to a spice model.

(3) Now you can create a custom component using this spice model as a basis within LTspice. Described here: http://www.linear.com/solutions/4678

(4) Generate an LTspice schematic using your custom component with the IBIS model, and run your simulation.
