Logic Analyzer Interface (LAI)
Intel is working with logic analyzer vendors to provide logic analyzer interfaces (LAIs) for use in
debugging Intel Pentium M processor systems. The following information is general in nature.
Specific information must be obtained from the logic analyzer vendor.
Due to the complexity of Intel Pentium M processor 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 an Intel Pentium M processor system that can make use of an LAI:
mechanical and electrical.
Mechanical Considerations
The LAI is installed between the processor socket and the Intel Pentium M processor. The LAI pins
plug into the socket, while the Intel Pentium M 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
Intel Pentium M 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.
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 analyzers 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.
