Power Calculator – Creating a New Project Without the NCD File
A new project can be started without the NCD file by either using the Wizard (as discussed above) or by selecting
the Create a New Project option in the Power Calculator – Start Project. A project name and project directory
must be provided. After clicking Continue, the Power Calculator main window will be displayed.
However, in this case there are no resources added. The power estimation row for the Routing resources is always
available in the Power Calculator. Users are then asked to add more information like the slice, EBR, I/O, PLL and
clock tree utilization to calculate the power consumption.
For example, to add logic resources (as shown in Figure 12-14), right-click on Logic >> and then select Add in the
menu that pops up.
Figure 12-14. Power Calculator Main Window – Adding Resources
This adds a new row for the logic resource utilization with clock domain as clk_1.
Similarly, other resources like EBR, I/Os, PLLs and routing can be added. Each of these resources is for AC power
estimation and categorized by clock domains.
