Number of bits: long long


Describe the length in bits of the C long long data type that the test hardware supports.

Category: Hardware Implementation


Default: 64

Minimum: 64

Maximum: 128

The number of bits that represent the C long long data type.


  • Use the long long data type only if your C compiler supports long long.

  • You can change the value for custom targets only. For custom targets, all values must be a multiple of 8 and between 64 and 128.


  • Enable long long enables use of this parameter.

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

  • The value of this parameter must be greater than or equal to the value of Number of bits: long.

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