Customizing a test instrument. A plurality of pairs of code modules may be provided. Each pair of code modules may include a first code module having program instructions for execution by a processor of the test instrument and a second code module for implementation on a programmable hardware element of the test instrument. For each pair of code modules, the first code module and the second code module may collectively implement a function in the test instrument. User input may be received specifying modification of a second code module of at least one of the plurality of pairs of code modules. Accordingly, a hardware description may be generated for the programmable hardware element of the test instrument based on the modified second code module.

Customizing operation of a test instrument based on information from a system under test

Customizing code modules of software and programmable hardware for a test instrument

A test system and method of configuring therefor. A test system includes a plurality of interface circuits for communicating with a device under test (DUT). The test system further includes a first memory for storing test vectors, a second memory for storing selection codes, and a third memory for storing configuration sets. Each selection code indicates an association between a test vector and a configuration set. Each configuration set may be associated with one or more of the test vectors. The configuration sets include information for configuring the interface circuits during communications between the test system and the DUT for each test vector. Each configuration set in the third memory is unique with respect to the other configuration sets, and the number of configuration sets may be less than the number of test vectors.
