Introduction
The SARC Schematic Editor, the symbolic computation of the transfer
functions and the SARC simulations are the work of Jacques Mequin.
The Napa Compiler and Package is the work of Yves Leduc.

Maxima is a descendant of Macsyma, the legendary computer algebra
system developed in the late 1960s at the Massachusetts Institute of
Technology.

The SARC Schematic Editor is the entry point to describe linear(ised) electrical circuits.
It is closely linked to the symbolic programming tool Maxima which is used to compute, in
the Laplace Domain, the transfer functions described by this editor and to mixed-signal
simulations with the Napa package.
Maxima can be used to postprocess further the transfer functions. The functions
produced by the pair SARC Schematic Editor/Maxima can be inserted in NAPA netlists.
The Napa Compiler is a compiler of netlists producing ad-hoc cycle-based ANSI-C
simulators of mixed signal circuits. It can host continuous domain models described in the
Laplace domain thanks to SARC (Semi Analytical Recursive Convolution).
The users’ guides of these tools are not the object of this paper and can be found on the
‘NAPA Vineyard’ Windows Panel created during the installation of the Napa package :
