Complete reliability verification for multiple-power-domain designs

With increasing design complexity and a heightened focus on reliability at all levels of integrated circuit (IC) design from intellectual property (IP) to full-chip, accurate and full verification coverage of the different reliability concerns within an IC design is essential. Designs containing multiple power domains add more complexity to reliability verification with the need to validate interactions between the different power domains. The Calibre® PERC™ packaged checks flow with pre-coded checks lets designers select and combine cross-power-domain electrostatic discharge (ESD) protection, electrical overstress (EOS), and level-shifter detection checks for their multiple power domain designs without worrying about coding a complex setup. Using the Calibre PERC packaged checks flow, design teams can shorten the IC design verification cycle while safeguarding product reliability.

As technology advances and the complexity of system-on-chip (SoC) functionality expands, multiple power domains are often required to support the design intent. Designing an SoC that includes both analog and digital circuits requires different voltages to support each power domain on the chip. On-chip communication between different power domains is required, but proper design techniques and protection must also be considered to ensure performance and reliability.

IC designs with multiple power domains present unique reliability verification challenges. Understanding how to detect and correct reliability issues in these layouts is critical to ensuring accurate, complete reliability verification for these designs. The Calibre PERC reliability platform provides a wide variety of pre-coded reliability-focused checks. With minimum setup, designers can easily use the Calibre PERC packaged checks flow to select and combine reliability checks for their multiple power domain designs without worrying about coding a complex setup. The simple selection and configuration of pre-coded checks maximizes ease-of-use and minimizes runtime setup.
