Abstract

1381413 Generating test patterns INTERNATIONAL BUSINESS MACHINES CORP 4 May 1973 [21 June 1972] 21222/73 Heading G4A A homing sequence for placing a sequential logic circuit in a predetermined state, compatible with testing by a testing sequence, is generated by data processing apparatus arranged to derive the sequence in reverse order from the total state (input variables and circuit state variables) corresponding to the desired set state. A sequence of total states is derived until a state having no circuit state variables is reached, this state defining the start of the homing sequence. Details of an algorithm for generating the homing sequence are described with reference to Fig. 5 (not shown). Specification 1,381,414 is referred to.
