Legato Reliability Solution
Industry’s first complete analog IC design for reliability solution
Key Benefits
- Improves test coverage of manufacturing test using analog defect simulation
- Advanced aging analysis better predicts device operating lifetime
- Performs dynamic electrothermal simulation of design to prevent thermal overstress during operation
- Analog defect simulation is integrated into the Spectre AMS Designer to enable simulation of mixed-signal design
- Based on Virtuoso custom IC design platform and Spectre Accelerated Parallel Simulator (APS) for fast, easy adoption
One of the most difficult challenges in analog IC design is the increased pressure to make sure mission-critical devices in applications like automotive, medical, industrial, and military/aerospace perform longer and more reliably in any condition or environment. Without a solid solution to solve these design challenges, the cost of failure can be very high and even life-threatening.
The Cadence® Legato™ Reliability Solution combines best-in-class Virtuoso® and Spectre® technologies to overcome design roadblocks and avoid failures in the field due to analog faults, device aging, electromigration, process variation, and thermal and packaging effects. The solution provides a confident design pathway to:
- Safety through simulation tools to detect failure and analysis of failure recovery for safety mechanisms
- Reliability with advanced degradation models enabling more accurate predictive device aging over time due to internal device and environmental pressures
- Quality to target 0 DPPM using automated defect identification tests to analyze results through the Spectre® Circuit Simulation Platform
Increased design complexity amplifies challenges. The Legato Reliability solution helps designers avoid these field failures and enables customers to achieve ISO 26262 certification through:
- Analog Defect Analysis: To reduce test cost and eliminates test escapes
- Electrothermal Analysis: To prevent thermal overstress and avoid premature failures
- Advanced Aging Analysis: To accurately predict product wear-out
