What Is WLR Test Software?

WLR Test Software helps you perform interactive and automated wafer-level reliability (WLR) stress testing.

Explore WLR Test Software Features

Wafer-Level Reliability (WLR) Test Software gives you access to NI’s massively parallel and flexible WLR test system that reduces cycle time and increases data insight velocity. The application software includes a test sequencer, device mapping, lot configuration tool, operator interface, and more. With this interactive software, you can easily perform 4-terminal and 2-terminal stress and measurement sequences on your structures and devices. WLR Test Software also provides LabVIEW and C# APIs for custom development and automated use cases.

Perform JEDEC Reliability Tests, No Coding Required

WLR Test Software includes a Soft Front Panel that is compliant with JEDEC standard test methodologies for WLR stress testing such as HCI, NBTI/BTI, and TDDB as well as debugging and monitoring automated applications. This software features a prebuilt and customizable operator interface. Additionally, the WLR Soft Front Panel includes an industry-standard test sequencer, prebuilt test step templates for WLR stresses, and abstracted parallelism and multithreading functionality. You also can log and generate reports using the built-in database tool.

Program PXI Hardware for Wafer Stress Tests

Wafer-Level Reliability Test Software is designed to be used with the PXIe-4135 precision SMU to provide faster insight with industry-leading channel density, parallelism, and measurement speed. The hardware can be packaged in a PXI system with up to 100-channels of high-performance SMU instrumentation and an SMU-per-pin architecture, giving you flexible connectivity for 2- and 4- terminal wafer stress tests at any test point, with 10 fA current resolution, pulsing modes, and up to 200 V/1A DC sourcing and sinking capabilities.

HOW TO BUY WLR TEST SOFTWARE

Required Products

TestStand is test management software that helps you develop, debug, and deploy test systems and provides full visibility into testing process and results. A TestStand Development System license is required to use the WLR Soft Front Panel.

LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights. A license for either LabVIEW Full or LabVIEW Professional edition is required to develop custom applications using WLR Test Software LabVIEW API.
