SLiCAP: a symbolic circuit analysis tool

SLiCAP: S ymbolic Li near C ircuit A nalysis P rogram, is a Free Symbolic Spice tool for deriving and solving design equations of analog electronic circuits.

A free open source (python) version of SLiCAP has now become available

Version 0.6 is the last release of SLiCAP for MATLAB users. This is because the core of SLiCAP is written in MuPAD code. This code cannot longer be maintained because The Mathworks removed the MuPAD notebook functionality. The alternative of using solely MATLAB code and MATLAB live scripts has been explored but rejected because of its extremely slow performance.

Development and support of SLiCAP for MATLAB will end in 2021.

Users are kindly requested to migrate (and contribute) to the new, open source version SLiCAP_python:

  • SLiCAP_python is written in python and maxima CAS.
  • SLiCAP_python is fully compatible with Jupyter notebooks.
  • SLiCAP_python performs faster than the MATLAB version of SLiCAP.

SLiCAP is used in all courses Structured Electronic Design offered by the TU Delft, Faculty of Electrical Engineering, Mathematics & Computer Science and the High Tech Institute.

  • Accepts SPICE-like netlists
  • Symbol libraries for netlist generation with LTspice, gSchem and lepton-eda (KiCAD in preparation)
  • Symbolic and numeric DC and statistical DC analysis
  • Symbolic and numeric Laplace analysis
  • Symbolic and numeric noise analysis
  • Accurate numeric pole-zero analysis
  • Library with device models
  • Many supporting functions for Structured Electronic Design:
    • Derive budgets for noise sources, GB product of OpAmps, number of stages in a feedback amplifier, offset and bias erros, etc.
    • Design negative feedback amplifiers using the asymptotic gain feedback model
    • Generate root locus plots with any circuit parameter as root locus variable
    • Calculate phase margin and generate Nyquist plots
