ASIC Design Methodology
CréVinn uses a structured top-down design approach called the "Fletcher Methodology". This technique was originally derived from Yourdon/De-Marco software design methodologies, by the pioneering work of Bill Fletcher of DAA (Design Analysis Associates, Logan, Utah).
The Fletcher Methodology provides us with several key advantages. As well as enabling well architected structured designs, it facilitates a strong team-working environment and provides well documented designs as a natural output of the process.

We have been using this technique with remarkable success over many years. Our long record of First Pass ASIC success and on-time delivery can be attributed to a significant degree to this methodology.

Benefits :
Architecture Right first time: No costly loops of
architectural changes required during detailed design stage.
Suits
Teamwork environment: Best ideas, optimal architecture emerges via
strong team synergy. Full team involvement leads to:
Better communications, so
fewer faults.
Flexibility: moving
engineers between functional blocks.
System-level understanding
motivates team to ensure system-level correctness.
Consistency across designs : Same design style, same
documentation format - facilitates porting functions between designs, re-use of
ASICs/cores.
Engineers familiar with the approach can move amongst
projects at short notice, and designers from other teams can instantly
contribute at design reviews.
