Logic Analyzer Interface (LAI)
Intel is working with two logic analyzer vendors to provide logic analyzer interfaces
(LAIs) for use in debugging Dual-Core Intel® Xeon® Processor 7100 Series processor
systems. Tektronix and Agilent should be contacted to get specific information about
their logic analyzer interfaces. The following information is general in nature. Specific
information must be obtained from the logic analyzer vendor.

Due to the complexity of Dual-Core Intel® Xeon® Processor 7100 Series processor-
based multiprocessor systems, the LAI is critical in providing the ability to probe and
capture front side bus signals. There are two sets of considerations to keep in mind
when designing a Dual-Core Intel® Xeon® Processor 7100 Series processor-based
system that can make use of an LAI: mechanical and electrical.

system that can make use of an LAI: mechanical and electrical.
9.1.1
Mechanical Considerations
The LAI is installed between the processor socket and the processor. The LAI pins plug
into the socket, while the processor pins plug into a socket on the LAI. Cabling that is
part of the LAI egresses the system to allow an electrical connection between the
processor and a logic analyzer. The maximum volume occupied by the LAI, known as
the keepout volume, as well as the cable egress restrictions, should be obtained from
the logic analyzer vendor. System designers must make sure that the keepout volume
remains unobstructed inside the system. Note that it is possible that the keepout
volume reserved for the LAI may differ from the space normally occupied by the Dual-
Core Intel® Xeon® Processor 7100 Series processor heatsink. If this is the case, the
logic analyzer vendor will provide a cooling solution as part of the LAI.

9.1.2
Electrical Considerations
The LAI will also affect the electrical performance of the front side bus; therefore, it is
critical to obtain electrical load models from each of the logic analyzer vendors to be
able to run system level simulations to prove that their tool will work in the system.
Contact the logic analyzer vendor for electrical specifications and load models for the
LAI solution they provide.
