Power Calculation and Average Power for large set of input combinations (in thousands)

mkza1002

Hello,

I want to know if there is  a method in Cadence to calculate power for thousands set of input combinations separately for a logic circuit design.

Also, is there a way we can do the same by using Verilog?

PS: basically in my case, the total input combinations is approximately 60,000.

Thanks.

  • In most tools, you will have default activity for each node in some form that equates to toggles over time. Alternatively and for more accuracy, you will be able to manually enter data or use an activity file. An activity file in formats like SAIF, TCF, VCD, FSDB, etc. will show each node and how they toggle over time per simulation vectors. Most tools will allow you to specify a window of those vectors to perform the average leakage and dynamic power analysis. If you wanted to a specific state without toggling, you can manually set the toggle and state on each node per your requirements. For details on how to do that, you would have to refer to documentation of specific tool.
