Method and algorithm for functional critical paths selection and critical path sensors and controller insertion
InactiveUS9536038B1CAD circuit designSpecial data processing applicationsDesign engineerCritical path method
CAD software examines delays of paths in a design from design engineers and first selects the longest paths. Then all paths that converge with these longest paths are examined for delays, and a fastest converging path is selected for each of the longest paths. The longest paths are again sorted by the fastest converging delay, and paths with slower converging paths are selected to be Functional Critical Paths (FCP's). Functional critical path timing sensors are added to each FCP to test setup time with an added margin delay. When the margined path delays fail to meet setup requirements, the functional critical path timing sensors signal a controller to increase VDD. When no failures occur over a period of time, the controller decreases VDD. The CAD software can replicate some of the FCP's and add toggle pattern generators and timing sensors and a margin controller to adjust the margin delay.

Automated cabling layout systems and methods
Automated cabling layout systems and methods are presented. A cabling assembly library stores multiple generic, design-tool agnostic cabling assembly objects representing cabling layout objects (e.g., cables, trays, mounts, conduits, etc.). The cabling assembly objects further include design rules governing the conditions of use of the cabling assembly object. Design engineers or designers can query the library to identify appropriate cabling assembly objects that would be appropriate for using within a modeled physical environment. One or more matching cabling assembly objects can be converted to an appropriate format for a design tool and instantiated into the modeled environment. The design tool can create modeled cabling layouts from the instantiated assemblies according to the design rules of the corresponding cabling assembly objects.

Optically improved CMOS imaging sensor structure to lower imaging lens requirements
ActiveUS7297916B1Lower lens requirementReduce thicknessTelevision system detailsSolid-state devicesVariable thicknessCamera lens
A sensor die that lowers the lens requirements by the use of a variable thickness distribution over the sensor die. The sensing portion of the sensor die has a different number of layers than the non-sensing portion of the sensor die. By reducing the thickness of each layer and / or eliminating one or more unnecessary layers in the sensing portion, the thickness of the sensing portion is reduced to lower the amount of stray light and allow an increase in chief ray angle as well as a decrease in the F-number of the imaging system coupled to the sensor die without compromising the image quality of the sensor die. Also, the thickness reduction provides the design engineers with extra allowance in handling the chief ray angle and F-number for a given lens requirements.

Bidirectional socket stimulus interface for a logic simulator
InactiveUS6421823B1Logical operation testingGeneral purpose stored program computerStimulus patternComputational logic
A communications socket between a logic simulator and a system for generating input stimuli based on the current state of the logic simulator is provided. Input stimuli to the logic simulator for use in implementing a particular circuit design simulation are calculated by interfacing an input program which models the function of the circuit being designed with the logic simulator. The lines in this input program are converted by an adaptive vector generator into communications signals which are understandable by the logic simulator so that the desired simulation may take place. The input program thus enables the adaptive vector generator to behaviorally model complex logical systems that the logic simulator model is only a part of and allows for more accurate and detailed simulation. The adaptive vector generator does this by determining the next input vector state in accordance with the present state of the logic simulator model as received from the communications socket. In other words, based on the state data received from the logic simulator, the adaptive vector generation automatically calculates the next stimulus pattern for the logic simulator model and provides this stimuli to the logic simulator through the communications socket. This technique removes the tediousness of the prior art techniques in that the design engineer no longer needs to specify every input step and to anticipate the output state of the circuit.

Controlling LED current from a constant voltage source
ActiveUS20150382421A1Optimizes current consumptionReduce the amount requiredElectrical apparatusElectroluminescent light sourcesDriver circuitControl signal
An LED driver circuit provides dimming control in LED lighting applications that can accommodate an AC / DC constant voltage converter. The driver circuit provides a dimming control signal that is used to directly control the DC output current of a downstream DC / DC converter driving an LED array. The dimming control signal tracks the AC or DC output from a dimming controller such that variations in the AC or DC voltage are reflected in the dimming control signal. This dimming control signal is then provided to the downstream DC / DC converter, bypassing the AC / DC constant voltage converter to directly control dimming of the LED array. Such an arrangement lets lighting design engineers deploy the familiar and well-understood constant voltage converter topology in LED lighting applications while retaining the ability to control dimming in the LED lighting applications.
