Variant 계층적 컴포넌트
R2026b계층적 Variant 블록을 사용하면 시스템의 모든 설계 대안을 하나의 모델로 나타낼 수 있습니다. 각 설계의 선택은 개별 계층 구조의 Variant 선택지로 모델에 포함됩니다. 이러한 모델은 고정된 공통 구조와 유한한 세트의 가변 컴포넌트를 가지며, 가변 컴포넌트는 Variant 제어에 따라 활성화되거나 비활성화됩니다.
예를 들어, 다음과 같은 세 가지 엔진 구성이 가능한 차량을 나타내는 모델을 시뮬레이션한다고 가정하겠습니다. 4-실린더 가스, 6-실린더 가스, 8-실린더 가스. Variant Subsystem 블록 내에 각 엔진 모델을 별도의 서브시스템으로 구현한 다음 사용자가 선택한 Variant 제어에 따라 서브시스템 간에 전환할 수 있습니다. 자세한 내용은 Introduction to Variant Controls 항목을 참조하십시오.
계층적 Variant 블록에 대해 생성한 코드에는 시스템의 모든 Variant 선택지가 포함될 수 있습니다. Activate Variant During Different Stages of Simulation and Code Generation Workflow 항목에 설명된 대로 코드를 컴파일하기 전이나 모델을 시작할 때 선택지 간에 전환할 수 있습니다. 계층적 Variant 블록으로 코드를 생성하는 방법에 관한 자세한 내용은 Variant 구조 (Simulink Coder) 항목을 참조하십시오.

Model Reference Variants
Use model reference variants. A Model block is used to reference one Simulink® model from another Simulink model. A Variant Subsystem block can contain Model blocks as variants. A variant describes one of N possible modes in which a Variant Subsystem block can operate. Each variant references a specific model with its associated model-specific arguments. For a given Variant Subsystem block, only one variant is active during simulation. You can switch the active variant by changing the values of variables in the base workspace or by manually overriding variant selection using the Variant Subsystem block dialog box.
