Claim 0:
1. A test system, comprising:
a margin tester including a plurality of interfaces for electrical connection to external devices, wherein at least one interface of the margin tester is configured to connect to a removable test fixture, the test fixture being external to the margin tester and configured to connect to a device under test (DUT);
the margin tester having:
one or more lanes connected to the at least one interface; and
a controller coupled to the at least one interface through the one or more lanes, wherein the controller is configured to establish a single-lane or multi-lane high speed input/output (I/O) link with the DUT via the test fixture, in which, for one or more lanes of the single-lane or multi-lane high speed I/O link, the controller implements physical and logical link layers that communicatively connect the margin tester with the DUT via the at least one interface and the test fixture, and to cause the margin tester to assess an electrical margin of the single-lane or multi-lane high speed I/O link in either or both transmit (Tx) and receive (Rx) directions.
