Technical Notes

Efficient Test Program Development with STDL and STPM
Verigy's software packages "SmarTest Data Link" (STDL) and "SmarTest Program Manager" (STPM) have been designed to generate initial test program setups for the V93000. Then SmarTest is used to debug the test program with devices.

STDL and STPM facilitate a simpler and more efficient development of an initial test program based on some new and unique features; for example, the capability to define safe settings for pins, automated integration of new test suites including reuse/merge of primaries, and a set of rules that gives the user control over the automated process.

This paper introduces the new concepts and features of STDL and STPM. It describes how to utilize the capabilities of the software packages, and how to set up the test program development flow in a structured way, so that the required time and effort is considerably reduced.

C++ Tips, Part 3
In this article, taking vector as an example, we will take a glance of how to utilize containers with assistance of iterators and algorithms in C++. With these examples, distinguishing features of C++ are introduced.

Flexible Test Cell Controller Architecture
Information is the lifeblood necessary to improve operations and performance at any level. As the semiconductor test industry matures it is implementing more advanced solutions to optimize business results. An emerging category of solutions targeted at Automatic Detection and Prevention of poor or non-compliant performance are built upon a rich set of data and control form the test cell. Critical insights are obtained from the synchronization and collection of manufacturing events, equipment events and product measurement data simultaneously.

This places increasing demands on the test cell controller to perform tasks that it was not originally designed for. New control sources, data sources, and monitoring systems are being added to the Test Cell at an increasing rate. The test system and the test cell control software must be flexible enough to coordinate and accommodate the data, monitor, and control requirements of each of these external systems. In order to support this interaction and to coordinate sometimes incompatible systems interfaces, a flexible, dynamic state engine driven control, and monitor capability is essential. Such an architecture will enable the test floor to adopt new optimization techniques incrementally without the need to replace their existing systems and infrastructure.

Test Methodologies

Mixed Signal Lecture Series: DSP-Based Testing Fundamentals 33: Interpolation
Data handled in DSP based testing is discrete data so that there is no data between adjacent data points. If you need to change the sampling rate of a waveform provided for an AWG, you may want to interpolate adjacent data points and create new data. For example, when the test signal waveform is automatically generated by a simulator and a specific sampling rate is already specified strictly, but the specified sampling rate or the data size is not suitable for your AWG on hand, you need to convert the waveform data for appropriate sampling rate and size. Then the original waveform is interpolated and re-sampled by a different sampling rate. This is the topic of this article. pdf, 7.5 MB
