A method includes inputting to a computer processor a search value. Bit values of bit element signals of a bus at a current time are determined time-ordered value pairs of timestamps and associated bit values of the bit element signals. Whether the bit values at the current time match values of corresponding bits of the search value is determined from the time-ordered value pairs. Data indicative of the current time and bit values of the bit element signals is output if the bit values at the current time match the search value. If any of the bit values at the current time do not match the search value, the current time is advanced to a later time indicated by a time-ordered value pair not matched to the search value and having a latest timestamp of the bit element signals that do not match corresponding bits of the search value.
