Abstract:
1. A trace system arranged in a system LSI (Large Scale Integration) to be subjected to trace, the system comprising: an event detecting unit for observing behavior of the system LSI to be observed and detecting an event to obtain observation data on the detected event; a first data reducing unit for performing first reduction processing on the observation data obtained by the event detecting unit according to a reduction condition; a second data reducing unit for performing second reduction processing, which is different from the first reduction processing, on the reduced observation data obtained through the first reduction processing performed by the first data reducing unit; an interrupt condition filter configured to make a matching notification when detecting an event that matches a set interrupt condition; and an interrupt control unit configured to perform control such as setting whether or not to make an interrupt notification to the second data reducing unit when receiving the matching notification from the interrupt condition filter, wherein the second data reducing unit controls the reduction condition for the first reduction processing of the first data reducing unit depending on the reduced observation data obtained by the first data reducing unit so that the reduced observation data has an amount of information processable by the second data reducing unit.
