launch cadence analog simulations from Matlab and extract a macromodel of linear analog functions

File Information
Description

In order to extract macromodels parameters, Cadence will be used as a schematic entry. The netlist will be used by the tool and simulations can be launched using the Ocean tool from cadence. By making DC, Parametric, and AC simulations, it is possible to extract a linear macromodel of the function (input and output impedance, transfer function) and even model the non linearities.

In a second part it is possible to make parametric simulation, i.e. change a variable in the schematic and plot all characteristics function of this variable.

With this methodology, it becomes possible to optimize, for example the sizes of the transistors, or current sources value easily.

Required Products Signal Processing Toolbox
MATLAB release MATLAB 7.10 (R2010a)
Other requirements Cadence tools - ICFB - Analog simulation (spectreRF)

Updates
16 Nov 2010

The graphical interface has been improved. Now the tool produces simulink and VHDL-AMS models

07 Dec 2010

In this new version, sources can be automatically added to extract the parameters.
