Software-Components (SW-C) are architectural elements that provide and/or require interfaces and are connected to each other through the Virtual Functional Bus to fulfill architectural responsibilities. The Software Component is the central structural element used when building a system at the VFB-level. A SW-C has well-defined ports, through which the component can interact with other Software Components.

A Software Component has a formal description defined by the Software Component template. Software Components can be abbreviated as SW-Cs.

A SW-C contains a Software Component Description (SWCD) and the implementation.

In Automotive SPICE V3.0 the term "software component" is used for the lowest level elements of the software architecture for which finally the detailed design is defined. A software "component" consists of one or more software "units".
