Basics of Simulation Technology (SPICE),

[attachment=17412]

SPICE Introduction


• SPICE
– Simulation Program with Integrated Circuit Emphasis
– Developed at University of California at Berkeley
– Three revisions, SPICE-3F5 is current
• Other simulation technologies
– XSPICE – behavioral SPICE – combines SPICE with component behavior in C
– VHDL – Programmable Logic Design
– IBIS – Used to model transfer function of sophisticated components (A/Ds, etc…)
– PSPICE, HSPICE – commercial variations of the Berkeley SPICE



SPICE Primer
• SPICE Circuit
– Built by creating a netlist of native SPICE primitive models.
– Netlist is a text file that lists all connections and model information.
– Schematic File
• Vendor specific
• May include package, footprint, and additional information
– SPICE adds analysis commands on top of SPICE file allowing a SPICE
simulation to extract information out of circuit (Transient, AC, Monte
Carlo etc…)
• Variety of native SPICE components:
– Resistors, Capacitors, Inductors, Sources, Transistors, etc…
• Subcircuit models
– Can be derived to make higher order components out of these simple
components
