Switching Characteristics
Use the interactive Excel-based EPE before designing your device to get a magnitude
estimate of the device power. The Quartus II PowerPlay power analyzer provides
better quality estimates based on the specifics of the design after place-and-route is
complete. The PowerPlay power analyzer can apply a combination of user-entered,
simulation-derived, and estimated signal activities which, combined with detailed
circuit models, can yield very accurate power estimates.
f For more information about power estimation tools, refer to the Early Power Estimator
User Guide and the PowerPlay Power Analysis chapter in volume 3 of the Quartus II
Handbook.
Switching Characteristics
This section describes performance characteristics of the core and periphery blocks for
Cyclone III LS devices. These characteristics are designated as Preliminary or Final,
as indicated in the title of each table. The designations are defined as follows:
■ Preliminary—Preliminary characteristics are created using simulation results,
process data, and other known parameters.
■ Final—Final numbers are based on actual silicon characterization and testing.
These numbers reflect the actual performance of the device under worst-case
silicon process, voltage, and junction temperature conditions.
Core Performance Specifications
Table 2–19 through Table 2–25 describe the core performance specifications for
Cyclone III LS devices.
Clock Tree Specifications
Table 2–19 lists the clock tree specifications for Cyclone III LS devices.
