5.4.2. Anti-Tamper Detection
Frequency tamper detection operates on the configuration clock source. To enable frequency tamper detection, you must specify an option other than Internal Oscillator in the Configuration clock source dropdown on the Assignments > Device > Device and Pin Options > General tab. You must ensure that the Run configuration CPU from internal oscillator checkbox is enabled prior to enabling the frequency tamper detection.
To enable frequency tamper detection, select the Enable frequency tamper detection checkbox and select the desired Frequency tamper detection range from the dropdown menu.
To enable temperature tamper detection, select the Enable temperature tamper detection checkbox and select the desired temperature upper and lower bounds in the corresponding fields. The upper and lower bounds are populated by default with the related temperature range for the device selected in the design.
To enable voltage tamper detection, you select either or both of the Enable VCCL voltage tamper detection or Enable VCCL_SDM voltage tamper detection checkboxes and select the desired Voltage tamper detection trigger percentage in the corresponding field.
