Automated Test Fixtures

Custom test-fixture design for automated validation of embedded serial communication buses.

Overview

We design purpose-built test fixtures that enable reliable, repeatable validation of I3C, I²C, and SPI interfaces across development, DVT, and manufacturing environments.

Why This Technology Matters

As embedded buses increase in speed and complexity, software-only validation is insufficient. Dedicated test fixtures ensure signal integrity, protocol compliance, and interoperability — reducing late-stage failures and improving manufacturing yield.

Why You Need It

If you're developing products with I3C, I²C, or SPI interfaces, custom test fixtures catch electrical and protocol issues that software testing misses. They're essential for DVT validation and production testing, where repeatability and speed matter. Without proper test fixtures, you risk shipping boards with intermittent communication failures.
