11. Design Security Recommendations

Follow these recommendations if you use the Drive-On-Chip Design Example as the basis for a commercial product:
  • Add more checks on current, voltage, and gain values in the design to ensure all the parameters are in the correct range.
  • Analyze the security risk of incorrect use of the JTAG interface while implementing the design. Incorrect use of the JTAG interface can cause system malfunction and damage the power electronics, motors, or machinery that the design drives. It might even create a hazard to people working with the design.
  • Ensure you follow guidelines for secure use of JTAG to protect the system from any unauthorized write or read accesses.
