GRL Announces Services for Analog and Mixed Signal Silicon Validation

Granite River Labs (GRL), a global leader in engineering services and test solutions for connectivity, today officially announced a comprehensive suite of services for pre and post-silicon validation of analog and mixed signal ICs, focusing especially on designs for demanding applications such as industrial, automotive and Internet of Things (“IoT”).  These services complement GRL’s capabilities for high speed SERDES characterization, and are available from GRL facilities in Silicon Valley, Shanghai, Bangalore, Yokohama, and Taiwan.

IC developers struggle to find the time and resources to thoroughly characterize their designs and meet aggressive tape-out schedules.  Budget pressures, smaller geometries, ever-lower power requirements, and noisy environments make the situation even more challenging.  For many analog and mixed signal designs, off-the-shelf test plans, methodologies and automation simply do not exist, and test programs are not straightforward to plan or execute.  GRL’s services offload stretched-thin teams, and include planning and managing all technical aspects and day-to-day test activities from start to finish, as well as automation scripts and debugging software tools for test repeatability and efficiency.

GRL’s services support pre and post-silicon validation of:

  • Microcontrollers
  • Sensing ICs, including MEMS (for optical, temperature, etc.)
  • Signal conditioning ICs including integrated Analog Front Ends (AFEs), switches, amplifiers, and muxes
  • I2C/SPI bus including General Purpose I/O, Analog to Digital/Digital to Analog Converters (ADCs/DACs), and display drivers
  • Power management/power monitoring ICs
  • Clocks, timers, and PLLs

Customers may flexibly mix and match specific services that best fit their needs, which may include testing in GRL’s facilities or development of methodologies and test environment for execution in the customer’s lab.

“Analog Bits’ world-leading, silicon-proven mixed signal IP solutions require the utmost performance and reliability,” said Mahesh Tirupattur, Executive Vice President at Analog Bits.  “Demanding  automotive applications require thorough IC validation, including intensive characterization under stressful temperature and voltage conditions.  GRL’s deep expertise in test development and execution has been critical to help us deliver automotive class IP solutions to market with confidence.”

“GRL is proud to offer highly customized programs to characterize complex analog and mixed signal devices,” said Miki Takahashi, GRL Vice President of Engineering.  “Our team excels at working without a ‘roadmap’ to develop test methodologies and setups from scratch based on an intimate understanding of a chip’s design and features, and helping our customers efficiently meet aggressive schedules to release robust devices into the market.”

GRL’s services include:

  • Signal and Power Integrity simulation and measurements
  • Test methodology development and test environment setup
  • Device characterization over Process, Voltage, and Temperature (PVT)
  • Debugging and PHY tuning
  • Project planning and management
  • Test automation development and integration
