Power Estimation Using the PowerPlay Early Power Estimator

PowerPlay Early Power Estimator for Altera CPLDs User Guide December 2010 Altera Corporation

Figure 2–6 shows the T-Flipflop.

Figure 2–7 shows an example of a 4-bit counter.

Routing

This shows the power of dissipation due to the estimated routing.

Routing power depends on placement-and-routing information, which is a function of your

design complexity. The values shown represent the routing power based on experimentation of

more than 100 designs.

For detailed analysis based on your design’s routing, use the Quartus II PowerPlay Analyzer.

Block

This shows the power dissipation due to the internal toggling of the LEs.

Logic block power is a combination of the function implemented and the relative toggle rates of

the various inputs. The PowerPlay EPE spreadsheet uses an estimate based on an observed

behavior across more than 100 designs.

For accurate analysis based on your design’s exact synthesis, use the Quartus II PowerPlay

Analyzer.

Total

This shows the total power dissipation. The total power dissipation is the sum of the routing

and block power.
