About AkkuratCore
AkkuratCore is a semiconductor IP company based in Dresden (Silicon Saxony). The company develops and licenses the AkkuratCore™ security architecture for chips in regulated environments: the application and security domains are physically separated — through Dielectric Trench Isolation (DTI) with a closed perimeter, irreversible E-Fuse fixing of the security rules during wafer test, and non-galvanic, capacitive or inductive coupling across Boundary Crossing Points. The ratio of isolation to active area (T_ratio) remains constant across all process nodes, which means the security proof is valid in a node-agnostic manner. The architecture is implemented as a System-in-Package with Island A and Island B as separate chiplets on a Security Interposer. Offerings include IP licensing, chiplet integration, design partnerships, RTL audit, tape-out support and silicon test vehicles. Application fields are critical infrastructure (KRITIS), smart meter gateways, automotive ECUs, MedTech, aerospace, robot safety and AI agent systems.

Architecture Principles and Methods
Dielectric Trench Isolation
Separates the application domain from the security domain through a closed dielectric perimeter.
E-Fuse Axiom Fortress
Security rules are burned in during wafer test and can be altered neither by software nor by firmware.
Boundary Crossing Points
All data paths between the islands run exclusively via capacitive or inductive coupling — with no galvanic attack path.
System-in-Package / Security Interposer
Island A and Island B integrated as separate chiplets on a Security Interposer.
T_ratio scale invariance
The ratio of isolation to active area remains constant across all process nodes.
RTL implementation
The specified core architecture is transferred into a Register-Transfer-Level design.

Security Proof
The architecture enforces security invariants outside software control: limits are physically sealed during wafer test, and according to the company a design audit is valid across all process nodes.
