RDC Methodology

The reset-domain-crossing signoff flow: reset intent, structural analysis, classification, fixing, dynamic checks, and closure.

  • 4topics
  • 4lessons

RDC methodology is the order of work that takes a chip from reset intent to a signed-off reset network. Each stage feeds the next: intent tells structural analysis what to check, classification turns findings into fixes or waivers, and dynamic checks confirm the fixes behave under real reset sequences.

Learning path through the RDC methodology topic.
Suggested order. Flow first, then intent, then classification, then closure.

Lesson

After it you can...

The RDC signoff flow

Name the six stages of RDC signoff and what each stage produces.

Reset intent and reset domains

Write down the reset intent a reset analysis needs.

Classifying RDC findings

Decide which findings are defects and which are acceptable with evidence.

Closure criteria

Say exactly what closed means for RDC and what evidence it needs.

Check yourself Why does classification come before fixing in the RDC flow?

Because not every finding is a defect. Classifying first sends real defects to fixes and acceptable findings to evidence or waivers, instead of fixing things that are already safe.
