ASIC Design Flow

Asic Design Flow

Leveraging our silicon-proven ASIC design services, expertise in multiple sensing technologies, and a flexible production model, STA proceeds efficiently from system-level requirements through ASIC specification, simulation, layout and fabrication. Our extensive experience with customers’ operational and regulatory environments, and their effect on analog and mixed signal ASIC based systems, enables a smooth transition of the final product from a controlled lab environment to its target market application.

ASIC Design Flow

System Review (CUSTOMER AND STA TEAM)

  • 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 operational requirements of the final product, not just the ASIC design, including any certification requirements such as CE, UL compliance.
  • Produce an ASIC block diagram
  • Produce ASIC based pcb block diagram that identifies each pin and any required external components.
  • Identify board level architectural tradeoffs that lead to most cost effective silicon integration
