the simulation (time=0). Entering a value a value greater than zero shifts the start point
to the right of the start of the simulation (time=0).
● Time Scale – allows the re-scaling of the expression for an item. The default value is 1:
no re-scaling. Entering a value less that 1 compresses the time scale so that the item’s
value changes occur more rapidly. Entering a value greater than 1 extends the time
scale so that the item’s value changes occur more slowly.
● New Expression – specifies an expression to use for the selected item from the list of
expressions used in the current plot. If you want to use an expression from another
simulation plot, you must first import the expression into your current plot (see
Exporting and importing plotted items).
Exporting and importing plotted items
The plotter display is a graphical representation of value changes for a set of items. Value
changes for items can be saved to a text file in value change dump (VCD) format (*.vcd)
for use in later STVD simulation plots. VCD files can be opened and edited in a text editor.
They can also be exported to and imported from other software that use this format.
You can easily select only the items that you want to export and import.
To Export plotted information for selected items:
1. Select File>Export to open the Simulation Data Export dialog box.
The Selectable field, displays an expandable list of all the items in the current plot. The
different display tabs are represented by folders.
