2.5 Setting Lock Bit Protection

The Configure Register Lock Bits option available in the Libero SoC Design tool is used to write-protect/lock user selected IP registers. Register lock bits are set in a text (*.txt) file, which the user then imports into the Libero SoC project. Use the following procedure in Libero SoC design tool to import the lock bit file into a design:
  • From the Design Flow window, double-click Configure Register Lock Bits to open the configurator.
  • Navigate to the text file (*.txt) that contains the register lock bits settings (see the following figure).
Subsequent FPGA bitstreams generated will have IP register lock bits set according to the file.
