This major release of the SSP standard provides support for FMI 3.0, as well as other enhancements in response to new end-user requirements for architectural design, traceability, incremental development, and support of Modelica models as components.
SSP 2.0 is a major version release, however all SSP 1.0 conforming artifacts remain fully conforming to SSP 2.0.
SSP 2.0 conforming artifacts are only conforming to the SSP 1.0 standard if they use a 1.0 version number and only use features available in SSP 1.0.
The following changes were performed as part of the 2.0.0 major release:
- Support for FMI 3.0
- Support for the new basic data types: Float32/64, and [U]Int8/16/32/64.
The binary data type was already supported in SSP 1.0. - Support for the new scheduled execution implementation kind in the component implementation attribute.
- Support for clocks as a new connector kind, and clocked variables/connectors.
- Support for arrays in connectors and connections in the SSD, as well as in the SSV and SSB file formats.
- Support for structural parameters with the new connector kind
structuralParameter. - Support for the redesigned alias variable handling in FMI 3.0.
- Support for the new basic data types: Float32/64, and [U]Int8/16/32/64.
- Architectural design features
- The component source attribute is now optional to support the usage of system structure descriptions for simulation architecture design without available component implementations.
- New connector kinds
local, andconstantare added to the specification, to support more encompassing interface specifications for components, and further parameter propagation. - Support for optional inner view connector coordinates, in addition to the outer view connector coordinates.
This feature enables more advanced graphical editing of SSP models.
- Traceability and meta-data features
- Integration of the
MetaDataelement developed as part of the SSP Traceability layered standard into the core standard, supporting the integration of arbitrary meta-data and digital signatures into the SSP file formats. - Support for mixed content in annotations, as in FMI 3.0 and the SSP Traceability layered standard.
- Integration of the
- Support for Modelica
- Support in the core standard for Modelica models as components
- Support for the mapping of complex Modelica types in interfaces to binary connectors in SSP
- General clarifications and bug fixes
