Extraction of SPICE Model Parameters from Atlas Device Simulation Using Utmost<\/strong><\/h1>\n

Many users would like to extract SPICE models from their process and device simulation using Athena <\/i><\/b>and Atlas <\/i><\/b>to be used in actual circuit simulation without actually fabricating the device.<\/p>\n

Using SILVACO’s Utmost <\/i><\/b>you can extract SPICE model parameters from the simulation results of Athena <\/i><\/b>and\u00a0Atlas<\/em><\/strong>.<\/p>\n

To guide users on how to go about extracting SPICE model parameters an example which extracts BSIM3v3 model from process\/device simulation is used in this article.<\/p>\n

All these commands can be executed from a single software \u2013\u00a0DeckBuild<\/em><\/strong>.<\/p>\n

The commands are heavily commented so that you know their functions and purpose.<\/p>\n

Here we will concentrate on the Utmost <\/i><\/b>batch mode commands. Here we only cover a very simple case and there is no local optimization. The\u00a0UTMOST<\/em><\/strong>\u00a0interactive mode can be used save the Utmost <\/i><\/b>setup into a file.\u00a0Utmost<\/em><\/strong>\u00a0interactive cannot be executed from\u00a0DeckBuild<\/em><\/strong>.<\/p>\n

# Commands that can be used in deckbuild to extract
\n# Spice model Parameters. The deck for TCAD is
\n# not complete . Below are examples of commands that
\n# maybe used in VWF Athena and Atlas to obtain the
\n# device characteristics<\/p>\n
