본 논문에서는 gem5 기반 SoC(System-on-Chip) 아키텍처 시뮬레이션 GUI 환경에서 GUI상에 구성한 아키텍처를 사람이 이해하고 유지보수할 수 있는(human-readable) 파이썬 스크립트로 추출(Export)하는 기능을 구현하였다. 기존 GUI 환경에서 추출되는 스크립트는 구성 요소가 평탄화되어 나열되는 형태로, GUI에 구성된 아키텍처의 계층 구조가 드러나지 않아 사람이 스크립트만으로 아키텍처를 파악하기 어렵다. 제안하는 Export 기능은 스크립트를 객체 정보 생성, 계층 구조 구성, 참조 파라미터 대입, gem5 메서드 호출, 포트 연결의 5단계로 구조화하여 생성함으로써 GUI에 보이는 아키텍처와 구조적으로 일대일 대응되어 추적이 용이하다. x86 및 ARM 기반 보드 실험을 통해 Export된 스크립트가 GUI 구성과 동일한 시뮬레이션 결과를 산출하며, 스크립트상의 파라미터 수정이 시뮬레이션에 그대로 반영됨을 확인하였다.
