Title: Concurrent logical and physical construction of voltage islands for mixed supply voltage designs
Inventor: COHN JOHN M
IPC: G06F17/50
Filed: 2001-11-15
Abstract: PURPOSE: A concurrent logical and a physical construction of voltage islands for mixed supply voltage designs are provided to mix supply voltage designs. CONSTITUTION: The method(100) begins when the unplaced design(105) is given to the placement tool. The unplaced design is described by a netlist, which is description of all of the gates and the connections between them. Along with the unplaced design, the tool is also given a set of timing constraints and/or power and area constraints. Also, as some circuits need to be in a certain location, there also need to be some location constraints. Finally, the placement tool is given libraries that describe the timing of the wire and the gates, and that contain the rules of placement, the size and shape of the gates, etc. Initially, all circuits are set to a particular voltage(110). Preferably, all circuits will be set to a low voltage, as the tends to decrease the overall power requirements. If the circuits are initially set to a higher voltage, the circuits are already higher power and the placed design tends to be higher in power. If more than two voltages are used, then it is recommended that the lowest voltage be chosen in the step. If two (high and low) voltages are used, the low voltage is chosen as the starting voltage for the voltage islands.

IPC: B60C11/00
Filed: 2001-11-20
Abstract: PURPOSE: A pneumatic tire is provided to reduce a noise with the minimum cost and effort by making stiffness of each pitch different as well as maintaining pitches of blocks. CONSTITUTION: A tread(10) is formed with plural blocks(10). The blocks installed on the tread are arranged in unit pitches(11,12,13) of large, medium, and small sizes. Stiffness of the unit pitches is formed differently by different formation of a rubber composition of the blocks. Stiffness of the blocks is formed between 40¯80 in the hardness of JIS. Difference of stiffness between adjacent pitches is formed in 10¯40 percents in the hardness of JIS. The pneumatic tire maintains pitches of the blocks and makes stiffness of each pitch different, thus noise is reduced with the minimum cost and effort.
