DVT IDE for VS Code SystemVerilog User Guide
Rev. 23.1.8, 29 March 2023
.dvt/default.build is an argument file that configures DVT's internal builder. By default, whenever a full build is performed, DVT starts by reading this file. It may contain:
Note: Unknown directives are ignored. In general, DVT-specific directives start with +dvt_. Unknown directives that start with this prefix are flagged with a warning.
The internal builder parses each top file, following includes/imports as specified by the language. Some directives ( parsing directives) allow you to control how files are compiled based on their extension, for example using System Verilog 1800-2012 for *.sv, Verilog 2001 for *.v, VHDL 1076-2008 for *.vhdl and e Language 1647-2011 parser for *.e. The parsing directives are either generic or mode specific.
Note: A project is built by analyzing source code with one or more of DVT's parsers depending on the Project Natures. Even if build configuration files in the .dvt folder specify certain files to be compiled with a specific language syntax, they will not be analyzed unless the corresponding nature is enabled for the project. The language syntax to project nature mapping is:
In general, the directives are similar with the arguments (or flags) that you would pass to any compiler/simulator.
A build file may include other argument files and so on. The internal builder follows the included files as it encounters them (as if part of a continuous stream). Note that the way a file is included (for example with '-f' or '-F') has an influence on how paths inside the included files are interpreted. For more details see Including Other Argument Files.
To simplify the flow integration, DVT supports several Compatibility Modes. This capability allows you to reuse existing arguments or argument files that you already use for a particular simulator invocation.
