  • Patent number: 9323875
    Abstract: A method is disclosed comprising using a circuit recognition engine running on a computerized device to detect a number and type of devices in an integrated circuit. The method characterizes device variation by selecting a set of dominant active devices and performing simulation using the set of dominant active devices. Three different options may be used to optimize the number of simulations for any arc/slew/load combination. Aggressive reduction uses a minimal number of simulations at the cost of some accuracy loss, conservative reduction reduces the number of simulations with negligible accuracy loss, and dynamic reduction dynamically determines the minimum number of simulations needed for a given accuracy requirement.

  • Patent number: 9157956
    Abstract: A plurality of digital circuits are manufactured from an identical circuit design. A power controller is operatively connected to the digital circuits, and a non-transitory storage medium is operatively connected to the power controller. The digital circuits are classified into different voltage bins, and each of the voltage bins has a current leakage limit. Each of the digital circuits has been previously tested to operate within a corresponding current leakage limit of a corresponding voltage bin into which each of the digital circuits has been classified. The non-transitory storage medium stores boundaries of the voltage bins as speed-binning test data. The power controller controls power-supply signals applied differently for each of the digital circuits based on which bin each of the digital circuit has been classified and the speed-binning test data.

  • Patent number: 9058034
    Abstract: Disclosed are embodiments of a method, system and computer program product for optimizing integrated circuit product yield by re-centering the manufacturing line and, optionally, adjusting wafer-level chip dispositioning rules based on the results of post-manufacture (e.g., wafer-level or module-level) performance path testing. In the embodiments, a correlation is made between in-line parameter measurements and performance measurements acquired during the post-manufacture performance path testing. Then, based on this correlation, the manufacturing line can be re-centered. Optionally, an additional correlation is made between performance measurements acquired during wafer-level performance testing and performance measurements acquired particularly during module-level performance path testing and, based on this additional correlation, adjustments can be made to the wafer-level chip dispositioning rules to further minimize yield loss.

  • Patent number: 8855993
    Abstract: Methods and systems perform a simulation on an integrated circuit design by applying a first value to a first variable and a second value to a second variable of the simulation to produce a first matrix corner simulation value. The methods and systems repeat the simulation using different values for the first and said second variables to produce a second matrix corner simulation value, a third matrix corner simulation value, and a fourth matrix corner simulation value. The methods and systems create a matrix, and the matrix has the first matrix corner simulation value, the second matrix corner simulation value, the third matrix corner simulation value, and the fourth matrix corner simulation value. The methods and systems interpolate all remaining values within the matrix based upon existing simulation values within the matrix.

  • Patent number: 8768679
    Abstract: A computer-implemented method that simulates NPskew effects on a combination NFET (Negative Field Effect Transistor)/PFET (Positive Field Effect Transistor) semiconductor device using slew perturbations includes performing a timing test by a computing device, by: (1) evaluating perturb slews in Strong N/Weak P directions on the combination semiconductor device for a timing test result; (2) evaluation perturb slews in Weak N/Strong P directions on the combination semiconductor device for a timing test result; and (3) evaluating unperturbed slews in a balanced condition on the combination semiconductor device for a timing test result. After each test is performed, a determination is made as to which evaluation of the perturbed and unperturbed slews produces a most conservative timing test result for the combination semiconductor device. An NPskew effect adjusted timing test result is finally output based on determining the most conservative timing test result.
