3.Click the Defaults button.

The system displays the simulators that were active when you last saved your cellview.

By default, spectre, spectreS, auCdl, and auLvs are selected on the Tool Filter form. You can override this default by setting auCore.toolFilter defaultTools in your $HOME/.cdsenv file. You can also change the default within your entire site by changing the dfII/etc/tools/auCore/.cdsenv file. For example, if you want to specify only spectre as the active default, add the following to your .cdsenv file:

auCore.toolFilter defaultTools string "spectre" nil

4.Select the tools for the Tool Filter display.
