1Reliability
If the circuit layout is designed with high degree of freedom to meet system specifications, then the circuit can conform to specifications, but the design process becomes extremely time-consuming due to numerous design options
Solution Approach 1:
The bridging circuit layout is divided into multiple sub-regions, each with specific design parameters. This segmentation allows the complex layout design problem to be broken down into manageable sub-problems, reducing the overall design time while ensuring specification conformance through systematic parameter optimization in each sub-region.
Solution Approach 2:
The invention performs preliminary electromagnetic simulation and extraction of electrical models before final layout completion. By predicting electrical characteristics early in the design process using simulated data, the system identifies potential specification violations before manufacturing, avoiding time-consuming redesign cycles.
2Reliability
If manual redesign is performed when layout does not meet specifications, then specification conformance can be achieved, but manufacturing efficiency is reduced
Solution Approach 1:
The invention implements a feedback mechanism where electromagnetic simulation results and electrical model extraction provide information about layout performance. This feedback loop allows automatic identification of specification violations and guides parameter adjustments in sub-regions, eliminating the need for manual redesign and improving manufacturing efficiency.
Solution Approach 2:
The invention replaces manual mechanical redesign processes with automated electromagnetic simulation and electrical model-based optimization. By using computational methods to predict and adjust layout performance, the system eliminates time-consuming manual iteration cycles while maintaining specification conformance.
3Measurement precision
If electromagnetic simulation and electrical model extraction are performed for each sub-region, then accurate layout rules can be obtained, but the complexity of the design process increases
Solution Approach 1:
The design process is segmented into sub-region analysis, electromagnetic simulation, electrical model extraction, and parameter optimization steps. This structured segmentation makes the complex process more manageable and systematic, allowing accurate layout rules to be derived through methodical analysis of each sub-region's electrical characteristics.
