DVT SystemVerilog IDE User Guide
Rev. 19.1.11, 16 April 2019
When you start Eclipse you are asked to indicate a workspace directory.
Each time you start Eclipse you can create a new workspace directory or indicate an existing one. You can create many workspaces, each one dedicated to some activity. You may use one workspace for developing your current project and another for maintaining the previous one. If the two activities are unrelated, in doing so you minimize clutter and improve performance by using two workspaces.
You can launch several Eclipse applications in parallel, but one workspace can be used only by one Eclipse instance that locks it (<workspace_dir>/.metadata/.lock). If you try to use an workspace already in use by an existing Eclipse instance, you'll be signaled "Workspace in use or cannot be created, choose a different one". You can switch at anytime to another workspace from menu File > Switch Workspace..., but launching different Eclipse for different workspaces is common practice.
