SILICON ASSURANCE

High-Coverage BIST &
Hardware Trojans

Accelerate burn-in and fault detection with cryptographic-grade pattern generation. Drift Systems replaces linear LFSRs with Arithmetic Chaos to hit corner cases and thermal limits 40% faster.


LAUNCH COMPARISON

1. Pattern Efficiency Comparison

Compare the fault coverage speed of a standard LFSR (Linear) versus the Drift Core (Chaotic). Watch how "Linear Dependencies" cause the LFSR to miss complex gate interactions, while Drift saturates the die.

FAULT COVERAGE
0.0%
CYCLES ELAPSED
0

Note: "Linear" mode simulates LFSR cyclic dependencies which leave coverage gaps.

2. Manufacturing & Security Capabilities

Reduced Test Time

Every second on the tester costs money. By generating Maximum Entropy vectors, Drift Systems triggers "Hard-to-detect" faults (resistive bridges, crosstalk) in fewer cycles than weighted LFSRs.

Trojan Activation

Hardware Trojans often hide behind "rare trigger" logic (e.g., "activate only if A, B, and C are high"). Drift's Ergodicity Guarantee ensures these rare states are visited, exposing the payload during test.

Secure Scan Chains

Prevent "Scan Dumping" of secrets. Drift can act as a Keyed Pattern Generator. Without the correct seed, the scan chain fills with chaotic noise, protecting IP from reverse engineering during test.

Chip Health / Aging

Drift sequences are sensitive to path delays. By measuring the "Drift Rate" of a specific logic cone, we can detect NBTI/HCI Aging (silicon wear-out) before it causes a system failure.
