Importing a Simulation File (VCD)
A post simulation VCD file can be imported into the Power Calculator project to estimate a design’s activity factors.
Under the File menu, select Open Simulation File and browse to the VCD file location and select Open. All AF
and Toggle Rate fields are then populated with the information from this file, as shown in Figure 12-14.
