SP1018G, A Cost-Effective Pattern Generation Alternative for Semiconductor Testing

Introduction

In the world of semiconductor testing, Automatic Test Equipment (ATE) is often associated with high performance—and high costs (ranging from hundreds of thousands to millions of dollars). For DFT (Design for Test) and QA engineers seeking a much more affordable yet capable solution, the SP1018G from the SP1000G Series offers an innovative alternative. With advanced pattern generation capabilities and scripting flexibility, the SP1018G provides a streamlined approach to testing and verification without the hefty price tag of traditional ATE systems.

Advanced Pattern Generation for Complex Testing

The SP1018G is designed to meet the needs of engineers working with intricate digital designs. While it does not natively support formats like WGL (Waveform Generation Language), STIL (Standard Test Interface Language), or VCD (Value Change Dump), it can be made to support these or any proprietary format through its powerful scripting capabilities. This flexibility ensures compatibility with a wide range of existing workflows and makes it adaptable to diverse testing needs.

Indeed, the scripting system has a syntax that is sophisticated enough to allow for optimized, 'code-like' pattern descriptions. For instance, it allows for up to 3 levels of nested loops (to repeat portions of a pattern) and it allows holding specific states for a fixed number of samples.

By combining the pattern generation with the logic analyzer and custom protocol decoding capability, one can build a complete test and reporting system. The image below shows an example of a JTAG test pattern after generation and automated decoding.

For proprietary pattern formats, the SP1018G excels with its scripting capability, allowing users to write and execute custom scripts. This adaptability makes the SP1018G a practical choice for testing high-performance digital ICs and verifying complex SoC designs.

Scripting: Flexibility at Your Fingertips

One of the most powerful features of the SP1018G is its scripting engine, which allows engineers to:

• Load Proprietary Test Patterns: Easily adapt unique patterns to the SP1018G, ensuring seamless integration into existing processes.
• Automate Test Sequences: Create scripts that eliminate manual setup, speeding up repetitive tasks and improving consistency.
• Integrate with External Tools: Synchronize the SP1018G with other test instruments, creating a cohesive and efficient testing environment.

The scripting system enables you to perform powerful tasks, such as loading files for read and write operations, developing custom GUIs, creating multi-page wizards, and provides many more features to adapt to your specific application and requirements.

Redefining Cost-Effective Testing

While ATE systems are often the go-to choice for high-volume production environments, the SP1018G offers a compelling alternative for prototyping, development, and low-to-medium volume testing. By providing essential pattern generation features and scripting flexibility at a fraction of the cost, the SP1018G empowers engineers to achieve their testing goals efficiently and affordably.

Conclusion
