Figure 2–9 shows a graphical representation of the thermal power consumption.
If you specify the I/O bank for the I/O pins in the I/O section, the PowerPlay EPE
spreadsheet estimates the current for each I/O bank based on the V
CCIO
settings.
Figure 2–10 shows the I/O bank parameter settings.
Table 2–9 lists the I/O bank parameters in the I/O worksheet of the PowerPlay EPE
spreadsheet, as shown in Figure 2–10 .
