XSpice Models

These are predefined analog device code models that are built-in to XSpice. Code models allow the specification of complex, non-ideal device characteristics, without the need to develop long-winded sub-circuit definitions that can adversely affect Simulator speed performance.

The supplied models cover the following functions, which are available for operation with either single-ended or differential voltage or current I/O:

Capacitance Meter

• Capacitance Meter (Single-Ended I/O)
• Capacitance Meter (Differential I/O)

Controlled Limiter

• Controlled Limiter (Single-Ended I/O)
• Controlled Limiter (Differential I/O)

Controlled One-Shot

• Controlled One-Shot (Single-Ended I/O)
• Controlled One-Shot (Differential I/O)

Current Limiter

• Current Limiter (Single-Ended I/O)
• Current Limiter (Differential I/O)

Differentiator

• Differentiator (Single-Ended I/0)
• Differentiator (Differential I/O)

Divider

• Divider (Single-Ended I/O)
• Divider (Differential I/O)

Gain

• Gain (Single-Ended I/O)
• Gain (Differential I/O)

Hysteresis

• Hysteresis (Single-Ended I/O)
• Hysteresis (Differential I/O)

Inductance Meter

• Inductance Meter (Single-Ended I/O)
• Inductance Meter (Differential I/O)

Integrator

• Integrator (Single-Ended I/O)
• Integrator (Differential I/O)

Limiter

• Limiter (Single-Ended I/O)
• Limiter (Differential I/O)

Multiplier

• Multiplier (Single-Ended I/O)
• Multiplier (Differential I/O)

PWL Controlled Source

• PWL Controlled Source (Single-Ended I/O)
• PWL Controlled Source (Differential I/O)

S-Domain Transfer Function

• S-Domain Transfer Function (Single-Ended I/O)
• S-Domain Transfer Function (Differential I/O)

Slew Rate

• Slew Rate (Single-Ended I/O)
• Slew Rate (Differential I/O)

Summer

• Summer (Single-Ended I/O)
• Summer (Differential I/O)

Notes

With the exception of the Multiplier and Summer functions (which are sub-circuit based variations of the models available in XSpice), the SPICE prefix for theses models is A.

All of the XSpice analog models can be found in the Simulation Special Function integrated library (\Library\Simulation\Simulation Special Function.IntLib). For more detailed information regarding XSpice, consult the XSpice User Manual or visit the Xspice website.
