DVT VHDL IDE User Guide
Rev. 20.1.26, 30 July 2020
In case you have updated DVT Eclipse and you want to go back to a previous installation checkpoint you can do that using: Help > About Eclipse > Installation Details > Installation History.
Using this page you can select a previous configuration and inspect the installed plugins and versions. If you decide to go back to one of the old configurations just select it an click Revert.
NOTE: Sometimes Eclipse might need the update site for the plugins involved in the revert operation, to add them go to Window > Preferences > Install/Update > Available Software Sites.
