The Simulink-SPICE-Interface was developed for the simultaneous simulation of
mixed systems containing Simulink-type and SPICE-type subsystems. The
Inteface works within the familiar MATLAB/Simulink environment and is based
on a Simulink feature to create new blocks written in C (C MEX S-Functions).
The source code of SPICE Version 3F5 was implemented in such a way.
Typical applications are:
- mechanical / hydraulical / electrical / electronic mixed
systems (i.e. automotive)
- aerospace / avionics
- environmental technology
- power system design
- biological / medical / biomedical systems

| Subsystem with interface block SLSP |
|
The new Simulink block SLSP is provided by the interface to:
- read a SPICE circuit file
- initialize the simulation
- perform the numerical integration
- manage the communication between Simulink and SPICE
|
One parameter of the new block SLSP is the name of a circuit file
which describes the circuit as a flat netlist.
The DATASHEET contains more
information and a complete application example.
