Number of bits: ptrdiff_t

ptrdiff_t bit length for test hardware

Model Configuration Pane: Hardware Implementation

Description

The Number of bits: ptrdiff_t parameter specifies the bit length of ptrdiff_t data for the hardware that you use to test code.

Selecting a device by using the Device vendor and Device type parameters sets a device-specific value for this parameter.

Whether the software checks the ptrdiff_t bit length for the test hardware or for the production hardware for a processor-in-the-loop (PIL) simulation depends on whether you select Test hardware is the same as production hardware.

  • When Test hardware is the same as production hardware is selected, the software uses ptrdiff_t bit length for the test hardware, specified in the TargetBitPerPtrDiffT parameter.

  • When Test hardware is the same as production hardware is not selected, the software uses the ptrdiff_t bit length for the production hardware, specified in the ProdBitPerPtrDiffT parameter.

Dependencies

This parameter is enabled only if you can modify it for the selected hardware.

Settings

64 (default) | 8 | 16 | 24 | 32 | 40 | 128

The ptrdiff_t bit length must be greater than or equal to the int bit length.
