TIMING CHART PROCESSING DEVICE

PROBLEM TO BE SOLVED: To provide a timing chart processing device capable of facilitating tracking of a branch relation of a timing chart including a conditional branch.SOLUTION: A timing chart processing device includes: input means; means for holding timing chart information indicating plural timing charts; means for holding branch source position information indicating a branch source position of each timing chart, branch destination position information indicating a branch destination position of each timing chart, and branch relation information indicating a relation between the branch source position and the branch destination position; means for holding a branch condition to go to one or more branch destinations at the branch source position; and means for displaying at least one of the timing charts. When the input means selects a branch condition, the display means displays a timing chart including a branch destination position to be reached according to the selected branch condition.
