8.1
Logic Analyzer Interface (LAI)
Intel is working with two logic analyzer vendors, Tektronix* and Agilent*, to provide logic
analyzer interfaces (LAIs) for use in debugging Mobile Intel Pentium 4 Processor-M systems.
Tektronix* and Agilent* or other qualified vendors 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 Mobile Intel Pentium 4 Processor-M systems, the LAI is critical in
providing the ability to probe and capture system bus signals. There are two sets of considerations
to keep in mind when designing a Mobile Intel Pentium 4 Processor-M system that can make use of
an LAI: mechanical and electrical.
8.1.1
Mechanical Considerations
The LAI is installed between the processor socket and the Mobile Intel Pentium 4 Processor-M.
The LAI pins plug into the socket, while the Mobile Intel Pentium 4 Processor-M 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 Mobile Intel Pentium 4 Processor-M 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.
8.1.2
Electrical Considerations
The LAI will also affect the electrical performance of the system 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.
