A circuit for diagnosing and debugging a processor for executing a stream of instructions that includes a set of debug registers for identifying an instruction or data address breakpoint; a processor for generating a debug exception in response to an instruction or data address in the stream of instructions matching the instruction or data breakpoint stored in the set of debug registers and a debug configuration register for enabling transfer of program control to one of a plurality of destinations in response to the debug exception. The debug configuration registers may designate system management mode, JTAG routine or a software debug interrupt handler as the destination.

Debug system allowing programmable selection of alternate debug mechanisms such as debug handler, SMI, or JTAG

An integrated circuit extraction tool for extracting sockets or microprocessors having a staggered pin grid array (SPGA) pin arrangement. Such tool includes an elongated base having a first end and a second end, each end forming a set of teeth that permit entry and extension of the teeth, diagonally, through the staggered pins of the socket or microprocessor. In the preferred embodiment, the first end is disposed at ninety degree with respect to the elongated base. Further, the elongated base is formed with a curvature to enhance the leverage action necessary for an extraction operation.
