The Logic sheet (see Figure 1) is used to estimate the power consumed in the CLB ower accounts for both the logic components and the routing. types of information should be entered:
- Enter the number of LUTs configured as Logic, Shift Registers and LUT-based RAMs and ROMs. If your design or a previous generation has been implemented within ISE or the Vivado Design Suite use the Import button in the Summary sheet to automatically import this information. Otherwise, use your experience to estimate usage required to implement the desired functionality.
- Enter the Clock domain this logic belongs to. Then enter the Toggle Rate the logic is expected to switch and the Average Fanout.
Signal Rate is computed in the following way:
To enter information on the Logic sheet related to distributed memory, you can use the XPE Memory Generator wizard, which appears when you click the Add Memory button on the Logic sheet. The XPE Memory Generator wizard provides a simplified method of adding memory-related rows to the Logic sheet.
