Introduction
The W2353EP/ET USB Compliance Test Bench helps solve the problem of simulation-
measurement correlation. In the past, the pre-manufacture design could be simulated and
tested using compliance tools from an EDA vendor. And the post-manufacture prototype could
be bench tested using compliance tools from test and measurement instrument vendors.
However, because of subtle differences between the two vendors independent approaches to
compliance, it was almost impossible to correlate the two. This opened the possibility of the
pre-manufacture design passing and the post-manufacture prototype failing, necessitating a
time-consuming and expensive design spin.
In contrast, USB Compliance Test Bench leverages the exact same industry-leading
Compliance App used on Keysight Infiniium oscilloscopes. It mimics a real hardware test bench,
and, using a scripting technology called “Waveform Bridge,” emits the same waveforms that
the Infiniium app receives when you are testing in your lab. Thus, the exact same tests – no ifs,
ands, or buts -- are applied to both the pre-manufacture simulated design and the actual post-
manufacture prototype.
