Astah UML vs BridgePoint

Astah UML has no write-up on Specifiction yet; its figures are above.

BridgePoint is a desktop tool suite for UML model editing, simulated execution, and translation in model-driven development. Built on Eclipse, it combines an editor, the Verifier, and model compilers. The Verifier runs and debugs models with stack tracing, variable views, stepping, and breakpoints. Compilers translate models into implementation languages such as C or SystemC and can conform to standards including IP-XACT, AUTOSAR, and MISRA-C. Modeling constructs provide ways to connect models to existing code and libraries. The Editor, Verifier, and Model Compilers are available under the Apache 2.0 license at no cost. Installable zip builds include the Eclipse and BridgePoint environment, so no prior software is required. BridgePoint supports Windows, macOS, and Linux, and includes class, component, state machine, interaction, activity, use case, sequence, and communication or collaboration diagram types. Nightly builds contain the newest code but are described as the least tested engineering delivery. Production projects can obtain BridgePoint Pro releases and support through a Service Pro contract.
