PowerPlay Early Power Estimator Input Values

Figure 3–1. Stratix PowerPlay Early Power Estimator Device & I

Standby Section

Standby

standby is the current consumed by the device after it is configured,

with no signals driving it and no interconnects toggling. The I

Standby

section of the PowerPlay early power estimator has both a typical and

worst-case value for each device (see Figure 3–2). The typical value is for

a typical process at 25º C. The worst-case value is for a fast process at

85º C.

1 Do not use the worst-case value as a maximum specification,

only as a guideline. Your device’s actual I

standby may vary

from what the PowerPlay early power estimator reports.
