Power Estimation and Management
Lattice Semiconductor
for LatticeECP/EC and LatticeXP Devices
Power Calculator Main Window
The main power calculator window is shown in Figure 12-4.
Figure 12-4. Power Calculator Main Window (Type View)
The top pane of the window shows information about the device family, device and the part number as it appears in
the Project Navigator. The V
used for the Power Calculation is also listed. Users have an option to provide the
CC
ambient temperature, and the junction temperature is calculated based on that.
Users can also enter values of airflow in Linear Feet per Minute (LFM) along with heat sink to get the junction tem-
perature. A table in the top part of the Power Calculator summarizes the currents and power consumption associ-
ated with each type of power supply for the device. This also takes into consideration the I/O power supplies.
In the middle pane of the window, there are two tabs:
1. Power View
2. Report
The first tab is the Power view. Under this tab, the Power Calculator tool has an interactive spreadsheet type inter-
face.
