Abstract:
1. A method for testing a time delay error ratio ER of a device against a maximal allowable time delay error ratio ER limit with an early pass criterion, whereby the early pass criterion is allowed to be wrong only by a first probability D 1 , comprising the following steps: measuring ns time delays (TD) of the device, thereby detecting ne bad time delays, which exceed a certain time limit, of these us time delays (TD), estimating a likelihood distribution giving a distribution of a number ni of bad time delays in a fixed number of samples of time delays (TD) as PD(ni, NE), wherein NE is the average number of bad time delays, obtaining PD wherein PD high is the worst possible likelihood distribution containing the measured ne bad time delays with the probability D 1 , obtaining the average number NE comparing NE if NE if NE
