Priority

Mandatory

Scope

MAAB

MATLAB Versions

All

Prerequisites

None

Description

A system must not have any:

  • Unconnected subsystem or basic block inputs

  • Unconnected subsystem or basic block outputs

  • Unconnected signal lines

In addition:

  • An otherwise unconnected input should be connected to a ground block

  • An otherwise unconnected output should be connected to a terminator block
