    摘要: An integrated system and method to achieve ESD robustness on an integrated circuit (IC) in a fully automated ASIC design environment is described. Electrical characteristics and electrical limits on the power network are translated to power route region constraints for each chip input/output (I/O) cell. Electrical limits on the signal network are translated into signal route region constraints for each chip I/O cell. These constraints are passed on to an I/O floorplanner (automatic placer of I/O cells) that analyzes trade-offs between these constraints. For I/O cells that can not be placed to satisfy both power and signal region constraints, the I/O floorplanner utilizes the knowledge of alternative power distribution structures to group I/Os and create local power grid structures that have the effect of relaxing the power region constraints. Instructions for creating these local power grid structures are passed on to the automatic power routing tool.

    摘要: Macro design techniques are disclosed for facilitating subsequent stage wiring across the macro. Whitespace areas within the macro are rearranged to accommodate the wiring. The rearrangement may take the form of physical rearrangement of the whitespace areas into routing tracks extending from one side of the macro to another; shielding using, for example, macro power bussing and/or macro wiring; routing power busses to the rearranged whitespace; and/or inserting active circuits with pins accessible to the wiring. In a preferred embodiment, active circuits are placed into rearranged macro whitespace during the design of subsequent stages. The rearrangement of the whitespace facilitates the wiring across the macro so that slew rate and path delay requirements of the subsequent stage wiring can be maintained, without excessive buffering or rerouting of wiring.

    摘要: A way of dynamically modifying error recovery on a communications controller to operate at the lowest power mode allowed by current error rate conditions. When operating conditions are good and a small number of errors are detected, a low power error detection/correction mode is entered saving battery life. The low power error correction mechanism runs at a slower frequency and lower power than the high power mechanism and maintains the same data rate for the controller, thus saving power. Selecting the controller error (power) mode may be externally, such as by a person using a control dial on a cellular telephone when the voice data gets too noisy. Alternatively, the selection can be automatic, a critical error level detector internally making the selection.
