The SCVD (Software Component View Description) files are formatted in XML and based on the schema file Component_Viewer.xsd.

The SCVD file format is described in the following sections:

XML elements : specifies the structure and top level elements of an SCVD file.
Symbol Access : explains how to refer to application symbols when reading program variables.
Data types : lists available scalar data types used in XML elements and explains how complex data types are defined.
Expressions : describes supported expressions for making calculations in an SCVD file.
Built-in functions : lists built-in functions that can be used for calculating stack memory usage, accessing CPU registers or application program symbols.
Value output : shows how to format output data for display in the Component Viewer or Event Recorder.

SCVD file validation

The schema file Component_Viewer.xsd. specifies the XML format. Use this schema file together with XML tools for validating an *.scvd file.

Using SCVD files in a debugger

The following steps explain how to use an *.SCVD file in the µVision Debugger. Other tools might require different steps:

Add the SCVD file to µVision as described in Manage Component Viewer Description Files.
Use the debug windows as described in Component Viewer.

SCVD files in software packs

Software components which are part of Software Packs may add related *.SCVD files directly in the Package Description file (*.pdsc) using the <file> element category other. In the *.pdsc file example below Network.scvd is added to the debugger when the component :Network:Core is selected. For details, refer to CMSIS-Pack - Pack Description (*.PDSC) Format.

<component CClass="Network" Cgroup="Core">
  <files>
    <file category="library"  name="Network/Lib/ARM/Network.lib"/>
    <file category="other"    name="Network/Network.scvd"/>
  </files>
</component>
