Transform Complexity into Simplicity
Satisfying the comprehensive requirements of the IEEE 802.3 clauses can be very complex. The list of tests and test conditions vary from
clause to clause, and each can be challenging to properly set up. The tests for each IEEE 802.3 clause vary, as do the test limits. An
example of one group of tests from clause 93 is below. The time for your test development team to read and interpret the specification
and then implement that understanding into test plans can take several months of effort.

Hosts and modules have unique interface
connectors and require compliance boards
or test adapters to enable connection
to test equipment. Designers endeavor
to minimize the trace lengths on the
compliance boards and cable lengths.
