Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for determining safe operating area (SOA) limits for circuit components like transistors are inaccurate, time-consuming, and lack integration with Electronic Design Automation (EDA) tools, failing to account for multiple degradation factors and requiring extensive redesigns.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional manual checking methods are used to determine SOA limits, then the process can be performed outside EDA tools, but the process becomes slow and time-consuming
Solution Approach 1:
The patent replaces manual mechanical checking processes with automated computational simulations integrated into EDA tools. The system automatically performs aging simulations and compliance checks using computer processors, eliminating the need for manual intervention and significantly increasing productivity while maintaining accuracy.
Solution Approach 2:
The EDA tool performs self-service by automatically generating SOA limits and conducting compliance checks without requiring external manual verification. The system uses built-in simulation engines and algorithms to autonomously determine operational limits and verify circuit designs, making the design process faster and more efficient.
2Adaptability or versatility
If conventional EDA tools perform aging simulations at the end of the design cycle, then the tool capability exists, but extensive redesign is required
Solution Approach 1:
The patent implements preliminary action by performing aging simulations and SOA limit determinations during the early stages of circuit design, before finalization. The system allows designers to check compliance with operational limits in real-time during the design process, enabling corrections to be made immediately rather than requiring extensive redesign after the design cycle ends.
Solution Approach 2:
The system provides continuous feedback to designers during the circuit design process by automatically checking compliance with SOA limits. The EDA tool generates real-time results from aging simulations and provides immediate feedback on whether the design meets operational requirements, allowing for iterative improvements without time loss.
3Device complexity
If conventional tools provide generic maximum operational voltage, then the analysis is simple, but the analysis lacks differentiation between Vds, Vgs, and Vbs
Solution Approach 1:
The patent applies segmentation by dividing the generic maximum operational voltage into separate, specific voltage limits for different transistor terminals (Vds, Vgs, Vbs). The system performs individual aging simulations and compliance checks for each voltage parameter, providing precise and differentiated analysis rather than a single generic limit.
Solution Approach 2:
The system implements local quality by providing customized voltage limits and aging simulation results for each specific transistor terminal and operating condition. Rather than applying a uniform generic limit, the EDA tool tailors the analysis to the specific requirements of Vds, Vgs, and Vbs, delivering precise local化的 operational guidance.
4Reliability
If separate calculation processes are used for each degradation mode, then the analysis can be thorough, but the process cannot analyze BTI and HCI collectively
Solution Approach 1:
The patent merges separate degradation analysis processes into a unified integrated framework. The EDA tool simultaneously performs aging simulations for multiple degradation modes (BTI, HCI, TDDB) within a single computational environment, allowing collective analysis of their combined effects on circuit performance while maintaining thorough reliability assessment.

AI summary
A non-transitory computer-readable medium comprising instructions executable by a processor to receive a set of input parameters related to a circuit component and perform an age-dependent analysis of the circuit component based on the set of input parameters. The age-dependent analysis of the circuit component includes performing a series of automated simulations of a non-aged model of the circuit component using each of multiple values of a first operational parameter, performing a series of automated simulations of an aged model of the circuit component using each of the multiple values of the first operational parameter, and comparing respective results of the automated simulations of the non-aged and aged models of the circuit component. The instructions are further executable to determine an operational limit for the circuit component based at least on the age-dependent analysis of the circuit component.
