This is semi-usable for debug, allowing for hierarchy traversal, port listings, and live value display.

You can build the full devtools version, which installs in extension/ locally.

./tool/gh_actions/devtools/install_devtool.sh

Then you can use the VSCode command Run Devtools in Browser and debug a live ROHD test being debugged in the current VSCode session because the details pane will maintain live port values for whatever level of hierarchy you want to observe.

If you want to debug a remote VSCode session, you can use the tasks that are built into the rohd_devtool_extension area or you can build it yourself. Either way you need to be in the rohd_devtool_extension/ subdirectory:

make web

and then use Flutter to start up the application (see the .vscode/tasks.json for the exact command).

Once started, you paste in the DTD address (or the port-forwarded version) and it will discover the VM debug sessions in that VSCode session, link, and retrieve the design hierarchy and current values (updated live).

This is a baseline framework to which we will add schematic viewing and live waveforms.
