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) 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.
