Power Estimation and Management
Lattice Semiconductor
for LatticeXP2 Devices
Creating a New Project Without the NCD File
A new project can be started without the NCD file, either by using the wizard (as discussed above) or by selecting
the Create a New Project option in the Power Calculator - Start Project. The 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. Additional information such as the Slice, EBR, I/O, PLL, and clock tree utilization
must be provided to calculate the power consumption.
For example, if the user wants to add the logic resources shown in Figure 10, right-click on Logic >> and then
select Add Row in the menu that pops up.
Figure 12-10. Power Calculator Main Window - Adding Resources
This adds a new row for the logic resource utilization with clock domain named clk_1.
Similarly, other resources like EBR, I/Os, PLLs and routing can be added. Each of these resources is used for AC
power estimation and categorized by clock domains.
Creating a New Project with the NCD File
If the post place and routed NCD file is available, the Power Calculator can use it to import accurate information
about the design data and resource utilization for power calculation. After starting the Power Calculator, the NCD
file is automatically placed in the NCD File option, if it is available in the project directory. Otherwise, browse to the
NCD file using the Power Calculator.
