Scan chain debugging, ATPG pattern generation, fault coverage, Gate-Level Simulation, IEEE 1149.x boundary scan, CTL generation and DFT sign-off methodology.

Revision 1.0Technical Engineering Reference

Why DFT sign-off discipline matters.

DFT evidence covering the stated mixed-signal IP sign-off methodology from scan and ATPG through GLS, boundary scan, CTL and closure.

The evidence is limited to the supplied methodology description; quantitative coverage or production claims are not added without approved source material.

What the architecture enables.

The DFT path connects test architecture and scan implementation to ATPG, fault coverage, gate-level validation, boundary scan and sign-off.

Structure test readiness

A defined DFT flow connects scan, ATPG and downstream validation activities to manufacturing-test objectives.

Improve debug visibility

Scan-chain debugging and gate-level validation provide structured checkpoints before sign-off.

Close fault coverage systematically

ATPG generation and fault-coverage analysis provide measurable closure activities within the stated methodology.

Support mixed-signal integration

Boundary scan and CTL-related activities support DFT integration around mixed-signal IP requirements.

Sign-off

DFT execution from architecture through sign-off.

AionSi can contribute to defined DFT activities from scan and ATPG through coverage analysis and sign-off readiness.

01

Scan and chain debug

Support scan-chain implementation, structural checks and debugging within the defined DFT methodology.

02

ATPG and fault coverage

Generate and analyze ATPG patterns and fault coverage against the stated sign-off objectives.

03

Gate-level validation
