1.3.5. Data Patterns
Power requirements depend on toggle % of the logic in your design. A clock-like data pattern has higher current requirements than a PRBS pattern. A PRBS pattern has higher current requirements than those for a grey-code pattern.
Use the highest toggle % that you expect to see in your design. The PDN design becomes difficult if you over estimate. Although it is design dependent, Altera assumes a 12.5% toggle percentage. Use the PPPA to analyze the toggle % of your design.
When using the Quartus PPPA, base your power estimations on simulation-based input data. It provides accurate power estimations.
