Compact Models for Integrated Circuit Design
includes the selection of an acceptable set of devices representing the entire
IC (integrated circuit) design space and selection of device characteristics
that account for the real-device effects to extract device model parameters
to modeling physical, geometrical, and ambient temperature effects on the
device performance in IC chips. The selection of devices and device characteristics for data acquisition is described in the following subsections.
12.2.1.1 Selection of Devices
In order to collect data for compact model parameter extraction, a set of
devices are selected, representing the entire design space to properly characterize the detailed physics of the device operation formulated by the target
compact model. These include devices to extract core model parameters

A generalized methodology to generate compact device model library for circuit CAD; each
task in the flowchart depends on the target device technology, target compact model, and the
target VLSI circuit for computer analysis.
