Low power design techniques are used in physical design to
minimize the power consumption of digital circuits and systems. The objective
of low power design is to reduce the power dissipation while maintaining or
improving the circuit performance. Some of the common low power techniques used
in physical design are:
Power gating: This technique involves turning off the
power supply to blocks of the circuit that are not in use, reducing the overall
power consumption.
Clock gating: This technique involves stopping the
clock signal to blocks of the circuit that are not in use, reducing the dynamic
power consumption.
Voltage scaling: This technique involves reducing the
operating voltage of the circuit to reduce its power consumption.
Multi-Vt cell libraries: This technique involves
using cells with different threshold voltages in the design to reduce the power
consumption.
Power-aware placement and routing: This technique
involves optimizing the placement and routing of the circuit to reduce the
power consumption.
Power-aware floorplanning: This technique involves
optimizing the floorplan of the circuit to reduce the power consumption.
Power-aware synthesis: This technique involves
optimizing the logic synthesis of the circuit to reduce the power consumption.
Power-aware testing: This technique involves
optimizing the testing of the circuit to reduce the power consumption.
These techniques can be used in combination to achieve a
significant reduction in power consumption in physical design.
