Solution Overview

Problem

Existing design platforms face challenges when evaluating multiple versions of PYTHON code due to compatibility issues and symbol conflicts, leading to errors during the generation of circuit layouts.

Innovation Solution

Implementing symbol versioning in the design platform by appending version suffixes to symbols in shared libraries, allowing multiple PYTHON interpreters to identify and use the correct symbols for their respective versions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple versions of PYTHON code are evaluated in the design platform, then the versatility and adaptability of the platform is improved, but symbol conflicts occur leading to errors in circuit layout generation

Engineering Contradiction:

Improveability to evaluate multiple PYTHON code versionsVSAvoiderror-free generation of circuit layouts

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the symbol space by creating version-specific symbol tables for each PYTHON interpreter version. Each evaluator maintains its own isolated symbol table that contains only the symbols compatible with its designated PYTHON version, preventing cross-version symbol conflicts while allowing multiple versions to coexist in the same design platform.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces version suffixes as an intermediary mechanism that mediates between multiple PYTHON interpreters and the symbol table. By appending version identifiers (e.g., @@PYC_2.6, @@PYC_3.8) to symbols, the system creates a naming convention that allows evaluators to distinguish and access the correct version-specific symbols, acting as a mediator that resolves version compatibility issues.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If version suffixes are appended to all symbols in shared libraries, then symbol conflicts are prevented, but the complexity of symbol management and library loading increases

Engineering Contradiction:

Improveprevention of symbol conflictsVSAvoidcomplexity of symbol management system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by having each PYTHON evaluator automatically identify and load only the symbols relevant to its specific version from the shared library. The evaluators use their version information to filter and select appropriate symbols autonomously, without requiring complex external coordination or manual configuration, thus reducing overall system complexity despite the presence of version suffixes.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent changes the parameter of symbol names by appending version suffixes, transforming a single unified symbol table into a version-differentiated symbol system. This parameter change allows the system to maintain a single shared library while providing version-specific functionality, managing complexity through systematic naming rather than requiring separate libraries for each version.

AI summary

A method for generating a circuit layout includes generating a plurality of symbols. Each of the plurality of symbols identifies one of multiple versions of code describing a circuit layout. The method also includes loading the plurality of symbols into a design platform used to compile the code describing the circuit layout. The design platform has evaluators for the multiple versions of the code. The method further includes generating the circuit layout described by the code using the design platform.
