DVT SystemVerilog IDE User Guide
Rev. 21.1.8, 1 March 2021
Some of the files that DVT compiles for a project may be located outside the project directory (see What is a Project). In order to benefit from DVTs advanced functionalities on such files, they are automatically linked as if inside the project, under the <project_root>/DVT Auto-Linked virtual folder. A virtual folder is a logical container - it has no physical representation on the disk.
For example, a file physically located in:
will be Auto-Linked under the following virtual folder hierarchy:
You can create new files or open existing ones anywhere in the DVT Auto-Linked hierarchy.
For creating new files, you can use the New File Wizard. The files thus created will have a representation on the disk.
For opening existing files, you can right click on any folder in the DVT Auto-Linked hierarchy and select Open from the context menu. A File Chooser will appear that will help you find the file that you want.
In the case of very deep hierarchies, you can define "aliases" for paths using the +dvt_auto_link_root+<alias>=<root_path> directive. These aliases are called DVT Auto-Linked Roots.
For example by adding this line in the project's default.build:
the following virtual folder hierarchy is created:
The specified <root_paths> and <aliases> must be unique, and therefore only the first occurrence is considered.
Aliases may not be names of directories located directly under the filesystem root (like for example /etc or /bin).
Environment variables may be used when specifying root paths, for example:
All auto-linked files with a path that starts with /a/b/c will be presented in DVT Auto Linked/hdl
The second directive will be ignored because the same "hdl" alias was used.
The second directive will be ignored because the same "/a/b/c" path was used.
All files under /a/b/c will be presented under src and the rest from /a/b under hdl.
