<div class="textblock"><p><b>SVDConv.exe</b> is a command-line utility to validate CMSIS-SVD files and to generate CMSIS-compliant device header files. <b>SVDConv.exe</b> is distributed with the <b>ARM::CMSIS</b> Pack (in the CMSIS\Utilities directory) together with the CMSIS-SVD schema file.</p>
<p><b>SVDConv.exe</b> performs the following operations:</p>
<ul>
<li>Checks the syntactical and structural compliance with the specified CMSIS-SVD format.</li>
<li>Checks the consistency, correctness, and completeness of the CMSIS-SVD file against the CMSIS-SVD schema file.</li>
<li>Generates CMSIS-compliant device header files, which can be used for software development.</li>
</ul>
<h2>Operation</h2>
<p><b>SVDConv.exe</b> is invoked form the command line. The general command format is: </p>
