摘要： An apparatus, a method, and a computer program product are provided for identifying signals in analogue electrical systems. The ID select signals that control the timing of this signal identification circuit comprise sequential numbers that count up and identify a corresponding signal. The signals to be identified are located on a group of input/output (I/O) pins. One multiplexer (first) selects a specific I/O pin in response to the ID select signals. An isolated voltage source is connected to this multiplexer and provides the selected signal to another multiplexer (second). The second multiplexer switches from this isolated voltage source to ground potential in response to the ID select signals. The isolated voltage source floats at the DC level of the selected I/O driver pin. Therefore, by connecting to the selected signal's I/O pin and the output of the second multiplexer, the selected signal can be identified and then probed.

摘要： A virtual electronic fuse (VEF) apparatus and methodology are disclosed that permit the state of an electronic fuse to change from an un-blown state to a blown state and then back to a virtual un-blown state. In one embodiment, the electronic fuse may change from the virtual un-blown state back again to a virtual blown state. The fuse apparatus includes multiple VEFs, each VEF exhibiting a respective address. The fuse apparatus also includes an address pool including multiple address pool locations. A fuse programmer stores an address of one of the VEFs in one or more address pool locations to indicate one or more state changes for a particular VEF. The fuse programmer may also store different VEF addresses in different address pool locations to indicate state changes for different VEFs.

摘要： In one aspect of the invention, a method for testing includes interposing a tester between first and second logic. The first logic and second logic have respective first and second output drivers. The tester operates in test cycles to detect dynamic contention responsive to a signal asserted by the first driver during one of the test cycles and a signal asserted by the second driver during an immediately succeeding one of the test cycles. Static contention is detected responsive to a signal asserted by the first driver during one of the test cycles and a signal asserted by the second driver during the same one of the test cycles.

摘要： An apparatus and method for memory bus tuning are implemented. A plurality of drivers having a plurality of selectable drive levels are coupled to a memory bus. The memory bus is connected to a memory device which may have a variable amount of memory, which may be in the form of dual-in-line memory modules (DIMM). A drive level is selected in response to a determination of the amount of memory included in the memory device. A register operable for receiving a data value corresponding to the amount of memory is coupled to the drivers, the drive level being selected thereby.
