A probe card assembly includes a probe card, a space transformer having resilient contact structures (probe elements) mounted directly thereto (i.e., without the need for additional connecting wires or the like) and extending from terminals on a surface thereof, and an interposer disposed between the space transformer and the probe card. The space transformer and interposer are "stacked up" so that the orientation of the space transformer, hence the orientation of the tips of the probe elements, can be adjusted without changing the orientation of the probe card. Suitable mechanisms for adjusting the orientation of the space transformer, and for determining what adjustments to make, are disclosed. The interposer has resilient contact structures extending from both the top and bottom surfaces thereof, and ensures that electrical connections are maintained between the space transformer and the probe card throughout the space transformer's range of adjustment, by virtue of the interposer's inherent compliance. Multiple die sites on a semiconductor wafer are readily probed using the disclosed techniques, and the probe elements can be arranged to optimize probing of an entire wafer. Composite interconnection elements having a relatively soft core overcoated by a relatively hard shell, as the resilient contact structures are described.

Methods and circuits for realizing a performance monitor for a processor from programmable logic
ActiveUS7308564B1Low costDigital computer detailsHardware monitoringProgrammable logic deviceLogical part
A performance monitor is realized from programmable logic on the same integrated circuit as a processor. A user may use a programming and analysis tool to select a performance monitor soft core and to program it into the integrated circuit. The performance monitor is used to debug and / or monitor operation of the processor. After the debugging and / or performance monitoring, the portion of the programmable logic used to realize the performance monitor can be reconfigured and used to realize another portion of the user-specific circuit. Because the portion of the integrated circuit used to realize the performance monitor can be later used in the user-specific design, the cost of having to provide a no-longer-desired performance monitor in each integrated circuit used in the user's design is avoided. Because the performance monitor is realized from programmable logic, the performance monitor is more flexible than a conventional hardwired configurable performance monitor.

An attribute of a hardware feature to be customized in a soft core is parameterized so that a value received from a user can be used to generate a description of a circuit containing the customized hardware feature. The generated description also describes, in accordance with the invention, a register that is indicative of the customization. For example, the generated (customized) description may describe the register as containing the value. After the circuit is created, the register may be read (at any time) to identify the customization. Hence, access to such a register eliminates the need for a user to maintain documentation on values specified during customization. Such a register may additionally be used to identify a device driver that is appropriate for use with the customized hardware feature. Additional registers may be included in the generated description, e.g. to identify the function of the circuit, and the version number.
