Using VBScript within the designer as part of the simulation setup you can configure the product to export data as simulation sweeps are completed. You will find commands in the “VB Scripting Reference Manual” that is linked to within the “Help Topics” in the Help Menu. However, this must be done at the design stage. There is not a way to batch export after the simulations are complete.
Which observers do you have and what data are you looking to export.
