1.6.9 Tamper

The Libero SoC tool automatically configures these building blocks based on the designer's configuration, removing complexities from the designer. When these features are not in use, the Libero SoC tool ties all the FPGA fabric sourced inputs to a disabled logic level through SEU immune, fabric flash bits. Libero SoC also sets the configuration registers to hold the block in reset. This macro has SEU immune, flash based, register level lock bits that can be enabled to avoid inadvertent changes to the configuration registers. This provides further assurance that the block configuration remains unchanged. For more information about registers and lock bits, see Device Configuration Report and Register Locks section.
