Signal Conversion

Convert a signal to a new type without altering signal values.

Library

Signal Attributes

Description

The Signal Conversion block converts a signal from one type to another. The block's Output parameter lets you select the type of conversion to be performed.

Data Type Support

The Signal Conversion block accepts virtual or nonvirtual signals of any data type.

Parameters and Dialog Box

Output

Specifies the type of conversion to be performed. The options are:

• Contiguous copy

• Converts a muxed signal whose elements occupy discontiguous areas of memory to a vector signal whose elements occupy contiguous areas of memory. The block does this by allocating a contiguous area of memory for the elements of the muxed signal and copying the values from the discontiguous areas (represented by the block's input) to the contiguous areas (represented by the block's output) at each time step.

• Bus copy

• Outputs a copy of the bus connected to the block's input.

• Virtual bus

• Converts a nonvirtual bus to a virtual bus. This option enables you to combine an originally nonvirtual bus with a virtual bus.

• Nonvirtual bus

• Converts a virtual bus that was originally a nonvirtual bus back to a nonvirtual bus.

Override optimizations and always copy signal

This option is enabled only for Contiguous copy conversion. Unless you select this option, Simulink eliminates the block from the compiled model as an optimization, if the elements of the input signal occupy contiguous areas of memory.
