Allows customers to achieve and validate safety requirements

Safety IP (Interface IP, Tensilica)

Certified Tensilica Processor Safety Package eases IP integration and device certification activities
IP certified as a SEooC against random failures to ASIL-B and ASIL-D standards
Hardware and software FuSa design and management processes certified to ASIL-D
ISO 26262 compliance certified by independent third-party assessors

ISO 26262 TCL Compliance

Cadence offers automotive Functional Safety Documentation Kits covering the full spectrum of semiconductor design and verification. The kits satisfy documentation requirements that the automotive component supplier must provide for their tools and flow to achieve ASIL certification. Additionally, the kits reduce the effort required to evaluate tool use cases within each of the supplier’s automotive design projects and help automotive component suppliers avoid the costly efforts of tool-qualification activities.
