System Review (CUSTOMER AND APPLICATION ENGINEER)

  • Review of the system schematics, block diagrams and specifications.
  • Develop an understanding of the design challenges, operating environment, and regulatory requirements, such as conducted/radiated noise, RFI, lightning and environmental exposure.
  • Understand the final product (not just the ASIC Design) including any certification requirements such as CE, UL compliance.
  • Produce an ASIC block diagram and board level diagram that identifies each pin and any required external components.
  • Identify board level architectural tradeoffs that lead to most cost effective silicon integration.
