Number of bits: long long
Bit length of C long long
data type for test hardware
Model Configuration Pane: Hardware Implementation
Description
The Number of bits: long long parameter specifies the bit length of the C
long long
data type that the test hardware supports.
Selecting a device by using the Device vendor and Device type parameters sets a device-specific value for this parameter.
Dependencies
To enable this parameter, select Support long long.
This parameter is enabled only if you can change its value for the selected hardware. Changing the value of this parameter is supported only for custom targets.
Settings
64
(default) | 72
| 80
| 88
| 96
| 104
| 112
| 120
| 128
Specify the number of bits that represent the C long long
data type for the test hardware. The value must be an integer multiple of 8
between 64
and 128
, inclusive. Different devices have different settings available for this parameter.
The value of this parameter must be greater than or equal to the value of Number of bits: long.
Tips
Use the long long
data type only if your C compiler supports long long
.
Recommended Settings
Application | Setting |
---|---|
Debugging | No impact |
Traceability | No impact |
Efficiency | Target specific |
Safety precaution | No impact when Test hardware is the same as production hardware is selected. If it is not selected, no recommendation. |
