Options for Power Estimation

  • Generate Value Change Dump (VCD) file script— Directs the EDA Netlist Writer to generate a script file that you can use to generate a Value Change Dump File in other EDA simulation tools. You can use the script to generate a Value Change Dump file when performing a simulation with the ModelSim, ModelSim-Intel FPGA Edition, NCSim, or VCS software.

  • Script settings— Opens the Script Settings dialog box which allows you to specify the signals that are included in the script file used to generate a Value Change Dump File in other EDA simulation tools. These signals are monitored and written out to the Value Change Dump File during simulation. The options for script settings are:
    • All signals— Directs the EDA Netlist Writer to include all output signals for entities and nodes in the design. Depending on the size of your design, this option may result in an extremely large Value Change Dump File.
    • All output signals except combinational lcell outputs— Directs the EDA Netlist Writer to include all output signals for entities and nodes in the design, except combinational outputs. This option results in a smaller Value Change Dump File. Intel recommends this option if your design targets a MAX® II device with the Vectorless estimation option during power analysis.

  • Design instance name— Specifies the test bench design instance name for simulation in EDA simulation tools. This option allows the EDA Netlist Writer to include the full path of the output signals in the script to generate the Value Change Dump File.
