Schematic Capture, Symbolic Solving, Processing, and Implementation of Analog and Digital Systems
"SchematicSolver is a kind of front processor for
Mathematica. It is a fantastic tool for researchers and
engineers in fields such as circuits, systems, and signal
processing. It is easy to use. You can draw your system on the screen
by picking up elements from the palettes using a mouse. Every time you
put an element on the workspace, it is automatically interpreted to a
corresponding Mathematica input statement called schematic

SchematicSolver is a Mathematica application package
that allows you to create symbolic representations of systems. It
provides functionality for system drawing, solving, simulating,
processing, and implementation.
The knowledge embedded in the representation can be used to generate
implementation code or to analytically derive system properties, such as
transfer functions or impulse responses. SchematicSolver is ideally
suited for linear, nonlinear, analog, or digital systems;
algorithm development; modeling; and simulation.
SchematicSolver also automatically generates software
implementations of linear and nonlinear discrete systems. This
function can process symbolic samples: for a symbolic input sequence,
you can compute the symbolic output sequence with both the system
parameters and the states specified by symbols. Similarly, the
transfer function of a complex multiple-input multiple-output (MIMO)
system can be derived in terms of system parameters kept as symbols.
For nonlinear systems, a closed-form expression of the output signal for
a known symbolic stimulus can be derived. Some classes of algorithms can
be visualized as block diagrams (systems) and optimized symbolically.
Schematic objects and symbolic processing can be applied to a much
wider range of tasks, such as intelligence amplification.
SchematicSolver automatically solves systems with algebraic
loops when the traditional numeric approach fails. Important
properties, such as the power-complementary property of high-speed
filters, can be analytically proved, which is practically impossible
to do by hand. Multirate systems can be symbolically treated in an
automated way by generating the schematic, creating implementation
code, and processing symbolic sequences. In addition, very complex
multirate structures can be compared.
Symbolic signal processing, an innovative feature of SchematicSolver
not available in other software, brings you computation of transfer
functions as closed-form expressions in terms of symbolic system
parameters and can find the closed-form response of schematics. The
derived result is the most general because all system parameters,
inputs, and initial conditions (states) can be given symbolically.
