DFT Engineering
for High Fault Coverage

Scan chain insertion, BIST architecture, JTAG integration, and ATPG pattern generation — structured to meet your test coverage and test time requirements.

DFT Engineering at Quantova
Overview

Testability Designed In, Not Bolted On

What is DFT? Every chip that comes out of a factory needs to be tested before it ships to customers. DFT (Design for Testability) is the engineering work done during chip design to make that factory testing fast, thorough, and cost-effective — so that faulty chips are caught before they reach products.

DFT added late in the design cycle costs area, performance, and schedule. Quantova integrates DFT planning from the RTL phase — defining test modes, scan architecture, and memory BIST strategy before implementation begins, so there are no late-stage surprises.

What We Deliver

Core Capabilities

Scan Insertion

Full-scan and partial-scan chain insertion with scan compression. Stuck-at and transition fault coverage targeting your test spec.

Memory BIST (Built-In Self Test)

March algorithm-based MBIST for embedded SRAMs and ROMs. Fault coverage and test time within your power and area budget.

ATPG (Automatic Test Pattern Generation)

Automatic test pattern generation with stuck-at, transition, and path-delay patterns. Pattern compression and simulation included.

JTAG Integration

IEEE 1149.1 JTAG boundary scan implementation and integration for board-level test and debug access.

Deliverables

What You Receive

  • Scan-inserted netlist
  • ATPG patterns and simulation reports
  • Fault coverage report
  • DFT architecture document
  • MBIST controller and test plan
DFT planning first: We recommend a DFT architecture review before RTL freeze. Late DFT insertion is expensive — early planning avoids it.

FAQs

Common Questions

Yes, but with constraints. Late-stage DFT insertion has area and timing implications. We assess the current state and advise on the most practical approach given your schedule.

We target the coverage specified in your test plan. Typical targets are 95-98% stuck-at fault coverage and 90%+ transition fault coverage.
