Functional safety and security in embedded systems

Conference: DVCLUB Europe | Verifying Safety in Automotive
Speaker: Nikita Gulliya, Agnisys
Speaker Title: Functional safety and security in embedded systems

A functionally safe design is able to continue operation or move to a safe state in the presence of faults such as alpha particle hits and silicon ageing effects. Safety design requires added logic, known as safety mechanisms, to detect errors and take corrective action. Based on user specification, IDesignSpec GDI or IDS-Batch CLI can generate the following types of safety logic included within the RTL design: Adding a parity bit(s), CRC, SECDED, TMR, error injection and checking the generated logic. The same safety mechanisms can be used to support a wide range of safety standards beyond ISO 26262 and IEC 61508, including DO-254 for aerospace, IEC 62304 for medical devices, and ISO 13849 for industrial equipment and industrial automation.

Key Points:

  • For the automotive and avionics industry, functional safety as mandated by the ISO 26262 and DO-254 standards are essential.
  • Adding Parity, CRC, SECDED, TMR, error injection mechanism and checking the generated logic.
  • Functional security method such as Lock, AES and bus protection
