ASIC Design Guide

ASIC design turns behavior, performance targets, and physical constraints into manufacturable silicon. This guide connects the decisions made at each stage so that RTL is not treated separately from timing, power, verification, or implementation.

Build a mental model of the complete design flow and understand what each stage must prove before tapeout.

What this guide covers

Follow the decisions in order, or open the module that matches the problem in front of you.

Specification to Microarchitecture

Translate product intent into measurable requirements, interface contracts, block ownership, performance budgets, and deliberate PPA tradeoffs.

  • Requirements
  • Interface contracts
  • PPA budgets

RTL design and integration

Express the partitioned design as deterministic, synthesizable RTL with explicit state, datapaths, pipelines, and flow control.

  • Datapaths and control
  • Pipelines
  • Ready/valid flow control

Clock, reset, CDC, and power

Engineer safe boundaries between clock and power domains while making reset behavior explicit and verifiable.

  • Clock domains
  • Reset strategy
  • CDC and low-power intent

Synthesis and timing closure

Constrain the real design, inspect synthesis quality, and close setup and hold timing across operating corners.

  • SDC constraints
  • Static timing analysis
  • QoR tradeoffs

Physical design and signoff

Carry logical intent through floorplanning, placement, routing, DFT, extraction, and final signoff checks.

  • Floorplan and routing
  • DFT
  • IR, EM, and equivalence

Apply the concepts

Move from reading to reasoning.

Use the question bank to explain assumptions, debug failures, and validate tradeoffs in the language interviewers expect.

Interview preparationPractice RTL design questionsWork through FIFOs, arbiters, CDC, resets, and reliable interfaces.

ASIC design, end to end

Connect design intent to signoff evidence.

A reliable ASIC flow carries requirements, interface contracts, and PPA budgets forward instead of rediscovering them after RTL. Each stage should make the next stage easier to constrain, verify, and close.

Use this guide to connect microarchitecture, clock and reset intent, synthesis, static timing analysis, physical design, DFT, and final signoff into one engineering argument.
