Method Summary

Modifier and Type	Method and Description
static Time	addTime(Time t1, Time t2)
static Time	adjustTimeUnit(Time time) This method takes a time (in value and unit) and adjusts the TimeUnit so that the value is as small as possible, without losing precision e.g. 1000us is converted to 1ms
static int	compareDataRates(DataRate r1, DataRate r2) This method is used to compare DataRate objects on the basis of their values (obtained in bit per second after applying the conversion based on DataRateUnit)
static int	compareTimes(Time t1, Time t2) This method is used to compare Time objects on the basis of their values (obtained in pico seconds after applying the conversion based on TimeUnit)
static BigInteger	convertToBit(DataSize size)
static BigInteger	convertToBitPerSecond(DataRate rate)
static BigDecimal	convertToHertz(Frequency frequency)
static BigDecimal	convertToMicroVolt(Voltage voltage)
static BigInteger	convertToPicoSeconds(Time time) This method is used to convert the value of Time/TimeObject element's value to BigInteger in Pico Seconds
static double	divideTime(Time t1, Time t2)
static EList<HwModule>	getAllModules(HwStructure struct)
static double	getAverageOfTruncatedNormalDistribution(Number a, Number b, double mean, double sd) Computes the average (mean) of the truncated normal distribution See Truncated normal distribution (Wikipedia)
static Time	getAverageOfTruncatedNormalDistribution(Time a, Time b, Time mean, Time sd) Computes the average (mean) of the truncated normal distribution See Truncated normal distribution (Wikipedia)
