proteanTecs RTSM ™
Driving the Path to Zero Failures

Functional Safety& Diagnostics

When Safety Is Non-negotiable
Software Defined, Electric, and Autonomous vehicles
are driving new roadmaps for advanced electronics.
Centralized architectures have introduced cutting-edge
ECUs and SOCs.

Coupled with stringent standardization, automotive
manufacturers and OEMs are tasked with achieving
functional safety in an ever developing landscape.
Maintaining safety standards without compromising
performance and cost becomes a critical challenge.

Automotive Industry Grade Safety Layer
RTSM is a novel real-time safety monitoring application for predictive and prescriptive maintenance,
allowing systems to stay always-on while receiving faster alerts on faults before they become failures.
By integrating RTSM, automotive manufacturers and OEMs can achieve unprecedented levels of reliability
and safety, aligning with evolving safety standards and industry expectations.

Prescriptive Maintenance at Hand
RTSM monitors the timing margin of millions of real paths in every chip at high coverage,
under real workloads. It alerts the system before reaching the minimal point at which
error-free functionality can be achieved.
