The authors are with Circuit Time Domain Reflectometry TDR measurements have always been the measurement approach of choice for board characterization work.

Based on TDR measurements, a circuit board designer can determine characteristic impedances of board traces, compute accurate models for board components, and predict board performance more accurately. For example, one of the key impedance profile features differentiating an open fault in the package or bondwire from an open fault in the die itself is a dip in the impedance profile corresponding to an input die capacitance and presenting itself shortly before the open impedance signature.

The presence of this characteristic dip in the impedance profile indicates a good connection to the die, whereas its absence indicates a problem in the package structure. Such a capacitive signature can be observed much more readily on the impedance profile waveform than on a raw TDR waveform.

In this report our focus is on locating short failures, using TDR-based fault isolation system. The failures include signal-to-ground shorts and plane-to-plane shorts.

Examples of plane-to-plane shorts may be a power plane to a ground plane short, or a short from one power plane to another, inside the package or inside the die. The visual nature of TDR makes it a very natural technology that can assist with fault location in BGA packages, which typically have complex interweaving layouts that make standard failure analysis techniques, such as acoustic imaging and X-ray [2], less effective and more difficult to utilize.

In this paper, we will discuss the use of TDR for package failure analysis work. We will analyze in detail the TDR impedance deconvolution algorithm as applicable to electronic packaging fault location work, focusing on the opportunities that impedance deconvolution and the resulting true impedance profile opens up for such work. Selecting the Package Modeling, Method, Derivations: You will have to customize the scripts to some extent to get them to operate effectively on your network.

These challenges include increased signal reflections, crosstalk, and losses that must be analyzed and understood in order for a memory system to function properly.

The accuracy of such simulation depends completely on the accuracy of the models for the interconnect components of the digital design, such as board traces, connectors and packages.

The accuracy of these models can be ensured with the use of TDR instrumentation, a very easy-to-use and intuitive technology for obtaining accurate models for the digital system components. However, it is well known that main memory subsystems haven't kept pace with the blistering speeds of the microprocessor clocks.

Although this gap has been bridged in part by improved and more sophisticated caches, data intensive images are demanding even more performance directly from the memory system.

Direct Rambus TM is a high-speed digital bus that requires circuit board traces to be impedance controlled at 28 ohms.

The traditional logic analysis measurement techniques now need to be complemented with a signal integrity measurement tool. Both single ended and differential measurements and modeling results will be presented. Time or Frequency Domain? To obtain accurate models for high-speed interconnects, a signal integrity engineer eventually needs to perform a measurement-based validation of the interconnect models.

At that point, a choice needs to be made about the type of test equipment to be used to accomplish the job.

Ease of use, accuracy, and cost are only a few of the attributes that will dictate the right instrumentation. The choice between these two sometimes moves to a more theoretical choice between time and frequency domain measurements.

Occasionally, it becomes a choice of personal belief in one domain being superior over the other. In reality, there are appropriate times for the use of both instruments. This paper will analyze the physics and mathematics of the relationship between time and frequency domain measurements. Practical aspects of testing will be discussed, as well as the ease of use and accuracy issues of the time and frequency domain measurement instruments.Summary In this paper we identified, based on expert user knowledge, accuracy requirements for SDNA debug, compliance, validation, and characterization applications.

In this article, we will discuss characterization of ATE fixturing using TDR measurement methodology, and offer some suggestions on how this characterization data can be used to avoid unnecessary test failures. Mismatches and variations can cause reflections that decrease signal quality as a whole.
