1. A method of tracing transactions on an integrated circuit chip, the method comprising, for each transaction:

  • extracting the transaction from interconnect circuitry of the integrated circuit chip, the transaction comprising an address signal and a data signal;

    applying a filtering condition to the address signal;

    only if the address signal does not fail the filtering condition, storing the address signal in an address trace buffer;

    storing the data signal in a data trace buffer;

    applying a triggering condition to the stored transaction; and

    outputting the stored transaction if the stored transaction matches the triggering condition.
