Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic design simulation methods are inefficient and time-consuming, particularly for complex circuit designs, as they require multiple iterations between schematic and layout changes, and fail to accurately capture transmission line effects and hierarchical structures, leading to difficulties in troubleshooting and understanding simulation results.
Innovation Solution
Implementing a net as a transmission line model in a schematic-driven extracted view, which allows for the generation of an extracted view that preserves hierarchical structures and enables direct modification and analysis, using transmission line model components and symbols to represent circuit components, thereby facilitating more accurate electrical behavior prediction and reducing computational resources.

Engineering Contradiction Analysis
1Reliability
If conventional layout extraction methods are used to generate simulation views, then simulation can be performed, but the graphical representations and hierarchical structures representing circuit component connections are lost
Solution Approach 1:
The patent creates a graphical extracted view that copies and preserves the hierarchical structure and visual representations from the original schematic design. The extracted view maintains the same hierarchical organization, graphical symbols, and connection representations as the source schematic, thereby preventing information loss while enabling simulation.
Solution Approach 2:
The patent segments the extracted view into hierarchical levels corresponding to the original schematic structure. By dividing the circuit representation into hierarchical segments (blocks, modules, individual components), the patent preserves the organizational structure and enables both simulation and visual understanding of the circuit architecture.
2Reliability
If multiple rounds of simulation with updated simulation views are performed after design changes, then design verification can be performed, but the process becomes very computationally expensive and time-consuming
Solution Approach 1:
The patent performs preliminary extraction of the graphical view and hierarchical structure from the schematic design before simulation. By pre-extracting and preserving the complete hierarchical representation, the system can quickly update and reuse the extracted view across multiple simulation iterations without re-extracting from scratch, significantly reducing computational time.
Solution Approach 2:
The patent creates a dynamic extracted view that can be efficiently updated when design changes occur. The hierarchical structure maintains its organization and can be dynamically modified to reflect changes in the schematic, allowing rapid reconfiguration for new simulation scenarios without complete re-extraction.
3Reliability
If layout extracted views are used for simulation, then simulation can be performed, but the extracted views are understandable by simulators but not much more beyond that, making them difficult to manipulate and understand
Solution Approach 1:
The patent creates a universal extracted view format that serves multiple functions: it provides simulation capability for electrical behavior analysis while simultaneously maintaining graphical representations and hierarchical structures that are easily understandable and manipulable by designers. The same structure supports both simulator processing and human interpretation.
Solution Approach 2:
The patent copies the familiar schematic design structure and graphical symbols directly into the extracted view. By using the same visual language, symbols, and hierarchical organization as the original schematic, the extracted view becomes immediately recognizable and easy to manipulate by designers who are already proficient with these representations.
4Productivity
If transmission line effects are not accurately captured in the model, then simulation is faster, but the electrical behavior prediction becomes inaccurate
Solution Approach 1:
The patent applies transmission line modeling selectively to specific portions of the circuit where these effects are most important. By identifying critical interconnects and applying detailed transmission line representations only where needed, the system maintains high accuracy for electrical behavior prediction while keeping the overall model computationally efficient.
Solution Approach 2:
The patent uses parameterized models that can adapt the level of transmission line detail based on the specific circuit conditions. By adjusting model parameters such as frequency, signal rise time, and interconnect characteristics, the system optimizes the balance between simulation speed and accuracy for different electrical behavior prediction scenarios.

AI summary
Disclosed are methods, systems, and articles of manufacture for implementing a schematic circuit design component as a transmission line model in a schematic driven extracted view for an electronic design. These techniques identify a schematic circuit component design form a schematic design of an electronic design and identify or determine layout device information of a layout circuit component design corresponding to the schematic circuit component design. An extracted view may be generated or identified for the electronic design at least by using a transmission line model based in part or in whole upon connectivity information or a hierarchical structure of the electronic design. The electronic design may then be modified or updated based in part or in whole upon results of performing one or more analyses on the extracted view with the transmission line model.
