Analog Behavioural Modelling is the process of creating an analog device from a description of its behaviour rather than its low-level design.
SIMetrix offers three way to create Analog Behavioural Models:
Verilog-A Modelling. Verilog-A is a compiled language that can be used to create sophisticated analog devices defined using non-linear equations, frequency domain definitions, time-domain events and other features. For further information refer to the Verilog-A Manual
Non-linear Transfer Function. This is a single device with a single-ended or differential output which generates a voltage or current expressed as a function of an arbitrary number of voltage and current inputs. See Non-linear Transfer Function
Laplace Transfer Function. This defines a linear device in the frequency domain using a Laplace transform with the 's' variable.. See Laplace Transfer Function
