 Logic Analyzer Interface (LAI)
Intel is working with two logic analyzer vendors to provide logic analyzer interfaces (LAIs) for use 
in debugging Mobile Intel Pentium 4 Processor-M 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 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.
