Validating pre post test
Even a delay of a few weeks can cost tens of millions of dollars.
Many complicated devices indicate their problems only after days or weeks of testing, and they produce a volume of data that would take centuries to reproduce on a simulator.Large semiconductor companies spend millions creating new components; these are the "sunk costs" of design implementation.Consequently, it is imperative that the new chip function in full and perfect compliance to its specification, and be delivered to the market within tight consumer windows.The basic set up for a Pre and Post Test Survey is pictured below.Respondents will start their response in a gateway survey that is used to create a unique identifier for each respondent.Let's say, for example, a university professor wants to gather information on whether, and, if so, how the thinking of students change due to taking her Race, Ethnicity and Identity class.
By collecting pre-test data on her students' attitudes at the beginning of the course and post-test data on their attitudes after the course she'll be able to measure any change in students' attitudes.
However, there are some tools that have been recently introduced to automate post-silicon system validation.
Simulation-based design environments enjoy the tremendous advantage of nearly perfect observability, meaning the designer can see any signal at nearly any time.
Pre-Test and Post-Test Surveys are a common practice in the surveying world. Then, at a later date, the Post-Test survey collects follow-up information after some treatment has been applied.
Usually, survey researchers would like for this data to be in the same survey so that they can easily make data comparisons in the analysis phase.
FPGA-based emulators, a well-established part of most implementation techniques, are faster than software simulators but will not deliver the comprehensive at-system-speed tests needed for device reliability.
