摘要： A method and apparatus are provided for a support interface for memory-mapped resources. A support processor sends a sequence of commands over and FSI interface to a memory-mapped support interface on a processor chip. The memory-mapped support interface updates memory, memory-mapped registers or memory-mapped resources. The interface uses fabric packet generation logic to generate a single command packet in a protocol for the coherency fabric which consists of an address, command and/or data. Fabric commands are converted to FSI protocol and forwarded to attached support chips to access the memory-mapped resource, and responses from the support chips are converted back to fabric response packets. Fabric snoop logic monitors the coherency fabric and decodes responses for packets previously sent by fabric packet generation logic. The fabric snoop logic updates status register and/or writes response data to a read data register. The system also reports any errors that are encountered.

摘要： In-band firmware executes instructions which cause commands to be sent on a coherency fabric. Fabric snoop logic monitors the coherency fabric for command packets that target a resource in one of the support chips attached via an FSI link. Conversion logic converts the information from the fabric packet into an FSI protocol. An FSI command is transmitted via the FSI transmit link to an FSI slave of the intended support chip. An FSI receive link receives response data from the FSI slave of the intended support chip. Conversion logic converts the information from the support chip received via the FSI receive link into the fabric protocol. Response packet generation logic generates the fabric response packet and returns it on the coherency fabric. An identical FSI link between a support processor and support chips allows direct access to the same resources on the support chips by out-of-band firmware.

摘要： A method for testing an electronic circuit comprises selecting a first log interval, a first log start pattern, a first log end pattern, and a first subset range of LBIST patterns from a plurality of LBIST patterns arranged in an order, wherein each LBIST pattern of the subset range of LBIST patterns causes an associated output of an electronic circuit. The method tests an electronic circuit in a first test by applying to the electronic circuit the first subset range of LBIST patterns sequentially in the order, thereby generating a first plurality of associated outputs. The method stores a first subset of associated outputs based on the first log interval, the first log start pattern, and the first log end pattern. The method compares the subset of associated outputs with known outputs to identify a first output mismatch.

摘要： A method and apparatus for pipelining clock control signals across a chip. The present invention avoids the need for multiple clock distribution systems by allowing clock controls for clock stopping, scanning, and debugging to be distributed to all local clock buffers through pipelined non-scan latches. The test control pipeline latches may be routed along with the clock through the clock receiver, the central clock buffer, and the sector buffer areas of the chip. A relatively low speed testing mechanism may be used to drive the testing of the chip externally. The test clock is synchronized with a free-running clock on the chip to allow the circuit to be operated at speed during the testing of the chip. During boundary scan, the pipelined controls are forced to static levels which are active levels for scanning. Non-pipelined signals control the boundary scan operation based directly on the TCK clock defined in the IEEE 1149.1 boundary scan standard.
