Programmable Power Technology Tiles Definition
Programmable Power Technology uses on-chip voltage regulators to enable Stratix® III, Stratix® IV, and Stratix® V core logic to be programmed at the tile level for high-speed mode or low-power mode configuration. Tiles are defined as:
- A combination of a LAB and MLAB pair
- A DSP block
- A memory block
- A column I/O interface
Tiles can be configured to operate in high-speed mode or low-power mode.
The Quartus® Primesoftware automatically controls which tile should operate at high-speed mode or low-power mode based on the timing constraints specified for the design. The power optimization, Programmable Power Maximum High-Speed Fraction of Used LAB Tiles and Programmable Power Technology Optimization options available in the Advanced Settings (Fitter) dialog box control the high-speed mode or low-power mode tiles configuration along with other power optimization techniques implemented at the Fitter level.
