Abstract: A method of partitioning an integrated circuit design for physical design verification includes steps of receiving as input a representation of an integrated circuit design having a number of physical design layers and a composite run deck specifying rule checks to be performed on the integrated circuit design. The composite run deck is partitioned into partitioned run decks so that the number of physical design layers referenced by each of the partitioned run decks is a minimum. The representation of the integrated circuit design is parsed to filter only the physical design layers required for each of the partitioned run decks into a filtered data deck for each of the partitioned run decks. The filtered data deck is generated as output for each of the partitioned run decks.

Abstract: The present invention is directed to a system for area efficient charge-based capacitance measurement requiring a minimum silicon area for probe pads. A structure block for the system includes several test structures coupled to a target test capacitance structure, a reference structure, and a logic block. Each test structure is coupled to a corresponding test capacitance structure. The logic block coupled to the several test structures selects a desirable test structure from the several test structures. The system may include several structure blocks and an additional logic block to select a desirable structure block. Each structure block includes a single output pin for busing each test output from the several test structures. In this manner, the silicon area may be minimized through reduction of the number of total pins and probe pads required.

Abstract: A measurement technique which allows the error components of the testing process to be eliminated by performing a differential-style measurement of the programmable termination resistor network. Since for any given DUT pin which is to be tested, there are multiple possible resistances to be measured, the test process provides that two or more resistance measurements are taken on the same pin. Once those values containing the error components are obtained, they are compared to generate a differential resistance measurement which contains only the actual on-chip DUT resistance with the error components completely removed. The differential value can then be tested against previously defined test limits that are set to guarantee the conformance of the on-chip resistance to the processing specifications. The technique can be applied at either the wafer sort or package test phase of device testing, with the different error components associated with either phase being eliminated.

Abstract: An arbitration elimination scheme for a bus. In a preferred embodiment, a programmable counter determines when a SCSI bus idle condition is reached and when a portion of an arbitration window for the bus has passed without participants. If there are no participants for arbitration, the SCSI initiator eliminates arbitration by asserting SEL and issuing initiator/target IDS. If any other device attempts to arbitrate at this time, the device sees SEL asserted and does not attempt to participate in arbitration.

Abstract: A system, circuit, and method are presented for adjusting a prefetch rate of a prefetch unit from a first rate to a second rate by determining a probability factor associated with a branch instruction. The circuit and method may determine the probability factor based on a type of disparity associated with the branch instruction. The circuit and method may further be adapted to calculate the second rate based on the probability factor. The ability to adjust the prefetch rate of a prefetch unit advantageously decreases the number of memory transactions, thereby decreasing the power consumption of a processing unit.

Abstract: A footprint based optimal characterization of intellectual property (IP) for more deterministic physical integration. The physical integration characteristics are based upon IP physical integration at an anchor point in a pre-defined IC platform. IP footprint characteristics are identified as fixed, variable or prioritized to each other, and bounding constraints are defined based on a set of characteristics for the IP, the platform characteristics and IC design requirements. The IP is physically synthesized using the bounding constraints. The synthesized IP is tested and the bounding constraints are iteratively modified until the characteristics of the synthesized IP are optimized/captured.

Abstract: An IC layout containing megacells placed in violation of design rules is corrected to remove design rule violations while maintaining the original placement as near as practical. The sizes of at least some of the megacells are inflated. The megacells are placed and moved in a footprint of the circuit in a manner to reduce placement complexity. The placement of the megacells is permuted to reduce placement complexity. Additional movements are be applied to the permuted placement to further reduce placement complexity.

Abstract: Boolean circuits are designed with minimal depth by calculating the depth of an existing circuit. Those subtrees having a non-regular root cell (i.e., cells having other than one child or having a child of a type different from the cell) are balanced by constructing a new subtree. The cells are then iteratively transformed with parent and/or grandparent cells to reduce the depth of the circuit. The transformation may include balancing the subtree to make the parent cell the same type as the selected cell, or by creating a new cell as parent to the selected cell.

Abstract: An audio calibration system includes control logic, an input device, a display, a noise generator, an inverter, a plurality of speakers, and a delay module coupled to each speaker. Upon receipt of a calibration start signal from the input device, the control logic directs the noise generator to produce substantially random noise which is then provided through the delay modules to each speaker. The inverter inverts the random signal to one of the speakers. Thus, in a two speaker system the sound emanating from one of the speakers is an inverted version of the sound emanating from the other speaker. At the points where the sound from each speaker combine, a “null” line is created as the two sources of sound cancel one another. The control logic controls the amount of delay introduced by each delay module into the sound provided to each speaker. By varying the amount of the time delay, the control logic can control the position of the null line to coincide with a listener's desired listening location.
