DDR4 Compliance Test Bench
Data Sheet
Introduction
The W2351EP DDR4 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 ap-
proaches 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, necessitat-
ing a time-consuming and expensive design spin.
In contrast, the DDR4 Compliance Test Bench leverages the exact
same industry-leading Compliance App used on Agilent 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.
