μblog: engineering from the trenches

Last week, I wrote an entry where I  pointed out some methods to aid with getting your SPICE simulation to converge and made a promise that I would write a guide that would go through all the necessary steps to create a simulation with a non-standard device. Luckily, the fine folks at Texas Instruments have already written such a guide. The guide is designed to work with the Orcad/Cadence suite and guides the user through all the steps, starting with downloading a SPICE model from ti.com to changing the appearance of the schematic symbol to creating a simulation profile and running the simulation. Although this is geared towards Texas Instruments, the ideas are generic enough to apply to practically any vendor’s models.
