Q-Star Test - Supply Current Monitors and Test, Measurement and Engineering Services

Q-Star Test is the world-leading provider of advanced IDD-based test and measurement solutions, is a provider of Test and Design For Test (DFT) consulting and training services and also offers engineering services for the development of customized solutions. We offer standard and customized products and services that support a total-solution test strategy, consisting of measurement equipment, consulting services and training courses.

Q-Star Test serves its customers with Test and DFT solutions, helping them to reduce test efforts and test costs whilst improving testability and product quality. Our products support standard as well as advanced IDD measurement strategies, such as various forms of Delta IDDQ, Current Ratios, and Relative IDDQ as well as transient current (IDDT) testing and current measurement-based tests for analog circuits.

IDDX MONITOR PRODUCTS, TEST CONSULTING AND TRAINING SERVICES

Q-Star Test has IDDX monitor products for:

• On-chip measurements of quiescent, transient and analog (supply) currents
• Power and ground connection / continuity verification
• "Plug-and-play" interface (loadboard - DUT board - probe card) applications; these are ATE independent solutions, enhancing the capabilities of existing ATE and offering a low-cost IDDX test technology entry point
• ATE integration

We offer consulting and training services on:

• Test and Design For Test (DFT)
• Design For Test (DFT) methodologies
• Test strategy improvement
• Supply-current based DFT methodologies and techniques
• Supply-current test application and measurement strategies

We offer engineering services for the development and realization of electronic measurement solutions and custom electronic modules or systems.

Our plug-and-play loadboard monitor products provide an easy way to implement a supply-current test strategy in an existing production environment.

LOADBOARD, BUILT-IN CURRENT AND ATE MONITOR MODULES

Loadboard monitor modules are plug-and-play single chip monitors or small monitor modules, to be placed on the interface board, loadboard, DUT board or probe card, providing ATE independent advanced IDD measurement solutions and extending the ATE functionality.

Q-Star Test offers the following types of loadboard monitors:

• Monitors for digital (IDDQ applications: QD-1000, QD-1010, QD-1011, QD-1010HC and QD-1020 - the QD-1000 is a single chip pass/fail IDDQ monitor with analog value read-back option and voltage or current based pass/fail reference setting and is offered with a QI-000x support module
• The QD-1010, QD-1011, QD-1010HC and QD-1020 are IDDQ monitor modules with pass/fail and digital value read-back option, digital pass/fail reference setting, on-board data processing capabilities and support various Delta-IDD and other advanced IDD test strategies - the QD-1010 and QD-1011 cover the 0mA to 30mA range, the QD-1010HC is designed for high current ranges (50mA to 2A) and the QD-1020 is a QD-1011 adapted for multi-site applications with resource sharing
• Monitors for transient / dynamic current measurements: QT-1400 and QT-1410; the QT-1410 offers a wide measurement range, high resolution, 50MHz sampling rate and digital interface and makes concurrent peak, charge and pulse-width measurements in its default configuration
• Monitors for analogue applications: QA-1000 and QA-1000HC

Built-in current monitors are IP building blocks that are integrated on the same silicon with the circuit to test. These monitor types comprise: the BICMON range of quiescent supply current monitors, the T-Mon series of transient current monitors and PG-Mon, a power-ground connection verification monitor.

ATE monitor modules are designed for integration into ATE or other test equipment. Prototypes are available, e.g. quiescent supply current monitors and transient / total supply current monitors.

TEST AND DESIGN FOR TEST (DFT) CONSULTING AND TRAINING SERVICES

Q-Star Test's consulting and training services are designed to shorten learning circles, improve productivity and to assist with the implementation of proper design for test and design for manufacturing flows. Our design-oriented consulting services address the following main themes:

• Test background, fault models and test pattern generation
• Design for Test methodologies and their application
• IDDQ related design, design for test techniques and IDDQ test pattern generation
• Optimization of supply-current test-based test pattern generation
• Use of built-in current monitors

Consulting services for test engineering and production testing include support for: test strategy improvement, supply-current test strategies and implementation, and IDDX-based test optimization.

Training services cover topics including, but are not limited to: "An introduction to Test and Design for Test for designers", “What is test all about?", “Fault modeling and test pattern generation", "Design for Test methodologies and their application", as well as "IDDX Design for Test strategies", "IDDX test strategies" and "IDDX test implementation".
