To our knowledge there is no such review on the web (if you find one,
please let us know!).

In two words: symbolic analysis.  PSpice is a numerical tool - you can
simulate your circuits numerically and display the results using graphical
post-processing tools (e.g. Probe).  Contrary to this, Analog Insydes uses
the symbolic capabilities of Mathematica to describe and solve analog
circuits - you obtain the results as mathematical formulas, for example

    Vout = R1 / (R1 + R2) * Vin

instead of Vout = 5V (as PSpice would).  (This is just a simple example.)

As a unique feature, Analog Insydes allows to automatically reduce the
complexity of such symbolic formulas in order to generate interpretable
expressions.  For validity checking you can perform the standard numerical
analyses as well as electrical engeneering plots with Analog Insydes, too.
Additionally, there are import and export filters to PSpice, Saber, and

Analog Insydes is not ment to be a substitute for PSpice or other numerical
circuit simulators.  Rather it is an additional tool which helps you to
solve problems going beyond the capabilities of numerical simulation.
