The present invention provides a breakpoint logic unit, debug logic and breakpoint method for a data processing apparatus. The breakpoint logic unit comprises a value storage operable to store data indicative of a selected value for an operational characteristic of the data processing apparatus, and comparator logic operable to compare the selected value with a value of the operational characteristic as generated by the data processing apparatus. The comparator logic then generates at least one result signal indicative of a match between that value and the selected value. A control storage is also provided for storing a match control value, such that if the match control value has a first value the comparator logic is operable to set the at least one result signal if a match is detected between the value and the selected value, whilst if the match control value has a second value the comparator logic is operable to set the at least one result signal if a match is not detected between the value and the selected value. Breakpoint generation logic is then operable to enable generation of an associated at least one breakpoint signal if the at least one result signal is set. This has been found to provide a particularly flexible and efficient technique for enabling a variety of breakpoint conditions to be programmed within the breakpoint logic unit.

A behavioral abstraction is, in an abstract sense, a generalization of an event cluster. Behavioral abstraction is a technique where a predetermined behavioral sequence is automatically recognized by the simulator in a concurrent stream of system events. A behavioral sequence is at its most basic level a partial order of events. However, the events considered in a behavioral sequence are subject to configuration-based filtering and clustering. This allows a designer to create a model for a particular behavior and then set up a tool to find instances of the particular behavior in an execution trace. Behavior models are representations of partially ordered event sequences and can include events from several components.

For a distributed and transparent debugging environment, a controller and an executor, each which accepts operations from a user, are disposed on each of plural computers. The controller and the executor each has a setting-status manager for managing the setting of a debugger and an execution-status manager for managing the execution status of a debugger. In response to a status change, the controller and the executor each notifies other computers of the content of the change via the network. A process manager manages a debug object program according to the content of setting and sets an operation status change due to detection of a break point to an execution-status manager. Meanwhile, the process manager changes its operation in response to a change in execution status sent from another computer.
