Interface modeling is one of the most important — and often confusing — aspects of SysML. In this guide, we walk through multiple ways to model system interfaces using proxy ports, interface blocks, signals, and connectors. Learn the difference between logical and physical interface modeling and how to decide the right level of detail for your system architecture.
Running simulations across multiple levels of a system model can be challenging. In this guide, learn how to use Black Box and White Box blocks in SysML to run simulations across system hierarchies, integrate subsystem models, and roll up values like mass using parametric diagrams.
When building systems in SysML, it is not enough to focus only on the current system of interest. This article explains why subsystem-level models matter, how internal block diagrams help define flows, and how systems must integrate upward into larger architectures like kitchens, houses, and beyond.
Proper system decomposition is one of the most important skills in SysML and MBSE. In this tutorial, we explore how to break a system into subsystems using a road bike example and compare poor and effective modeling approaches.
Activity diagrams in SysML are rarely perfect on the first attempt. In this tutorial, we walk through how to refine activity diagrams step-by-step using a NASCAR racing example, showing how simple behavioral models can evolve into more realistic system logic.
Constraint blocks are a key part of SysML parametric modeling. In this tutorial, learn how to model multiple equations within a single constraint block, compare different modeling approaches, and run simulations using parametric diagrams.
Learn how to build a SysML parametric diagram from scratch using constraint blocks and value properties. This step-by-step tutorial demonstrates how to calculate lightning strike distance from thunder timing using Cameo Systems Modeler.
Learn how to send structured messages in SysML using blocks, signals, operations, and interface blocks. This tutorial explains multiple parsing methods, signal handling, flow properties, and subsystem-to-subsystem communication in Cameo.
Learn how SysML state machine diagrams work using a practical oscillating fan example. This tutorial explains states, transitions, guards, shallow vs deep history, orthogonal states, and how to refine a state machine through simulation.
Learn how SysML internal block diagrams work using practical examples like a toaster and iPhone charging system. This tutorial explains parts, ports, signal flows, ICD tables, proxy ports, autowiring, delegate ports, and simulation in Cameo.
