20140068364 | MODIFIED CONDITION/DECISION COVERAGE TEST CASE AUTOMATION - This embodiment relates to software verification and in particular to automatic generation of Modified Condition/Decision Coverage (MC/DC) tests scenarios. A system and method for reducing Modified Condition/Decision coverage (MC/DC) test scenarios is described along with selection of test data automatically for an input Boolean expression. An MC/DC test case engine generates optimal test case for a Boolean expression using an algorithm. The optimal minimal number of MC/DC cases generated to for satisfy the MC/DC condition for ānā number of inputs may be ān+1ā. The MC/DC test engine supports Boolean expression with Arithmetic and Comparison operators. The MC/DC test engine supports Boolean expression with no limitation on number of input variables | 03-06-2014 |

20140300427 | LOOKUP TABLE ASSISTED PULSE WIDTH MODULATION - Embodiments are directed to modulating a pulse width modulation (PWM) signal, by initializing at least one phase index to an initial value, establishing a set of values in a lookup table that correspond to data points for PWM comparator values that correspond to a given number of samples of a single periodic waveform during a predetermined sampling rate that establishes a table resolution, repeatedly executing the following operations at the predetermined sampling rate: determining a value of a command signal frequency, setting a value to a jump factor equal to the quotient of the value of the command signal frequency divided by the table resolution, progressing the value of the phase index by the value of the jump factor, selecting a value of a commutation vector from the lookup table that corresponds to the phase index, and loading the value of the commutation vector into a corresponding PWM comparator. | 10-09-2014 |
