Title:
WAVEFORM GENERATOR AND TESTING APPARATUS USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2010/026616
Kind Code:
A1
Abstract:
Timing setting data (T1-Tn) include an arbitrary combination of set timing signals (S), which are indicative of the timings of positive edges, and reset timing signals (R) which are indicative of the timings of negative edges. A sorting part (30) sorts the n pieces of timing setting data (T1-Tn) according to the order of the timings indicated by the respective pieces of timing setting data (T1-Tn). An open processing part (33) refers to the sorted timing setting data (TS1-TSn) to detect two consecutive set timing signals (S) or two consecutive reset timing signals (R) and then nullifies one of those consecutive set timing signals (S) or one of those consecutive reset timing signals (R). An edge assigning part (34) assigns the non-nullified remaining set and reset timing signals (S, R) to the respective ones of m set variable-delay circuits and m reset variable-delay circuits in ascending order of the numbers of past usages thereof.
