Neurealm delivered firmware development and software validation automation for a Tier 1 semiconductor company. The project centered on the functional validation of a sophisticated Audio DSP algorithm within an Integrated Circuit (IC). By architecting a specialized automation environment, Neurealm ensured the algorithm’s reliability across diverse use cases while significantly optimizing the testing lifecycle.

Business Context

The client required a rigorous validation process for a complex audio algorithm to ensure high-fidelity performance in silicon. Key project drivers included:
Complex Validation Needs: The sophisticated nature of the DSP algorithm demanded validation across a wide variety of scenarios.
Efficiency Requirements: There was a critical need to reduce setup and execution time to accelerate the product development timeline.
Full Lifecycle Testing: The scope spanned both pre-silicon (on FPGA) and post-silicon functional validation to ensure hardware-software parity.

Solutions

Neurealm implemented a technology-driven validation framework using industry-standard tools and custom automation:
Hybrid Automation Environment: Developed a unique environment where hardware modules and Matlab models coexist, allowing for seamless comparison and verification.Advanced Scripting & Analysis: Utilized MATLAB for scripting measurement algorithms, analysis, and overall environment automation.
Data Capture & Hardware Platforms: Employed National Instruments DAQ for analog data capture and an FPGA platform for early-stage pre-silicon validation.
End-to-End Test Management: Managed the entire cycle of test script development, execution, and comprehensive result analysis.
