The connection between both motions
The IP you license standalone is the exact same IP inside every chiplet we design.

Every PCIe Gen 6 Subsystem, CXL 3.0 Subsystem, and NoC block in our standalone catalog is also a building block in every Compute, IO, and Memory Expander silicon engagement. License the IP now. Commission the chiplet when you're ready to scale.

Microarchitected for PPA.

Every SignatureIP block is microarchitected from first principles to be modular, reusable, and PPA-optimized.

LP

Low Power

Power domains designed modularly at the microarchitecture level. Active, standby, and retention states built into every IP block. PCIe Gen 6 and CXL 3.0 deliver the low-power implementations on the market.

OL

Optimal Latency · Optimal Throughput

NoC topologies generated by iNoCulator™ are latency-optimal and throughput-optimal by construction.

HP

High Performance

Backward compatible Gen 6 to Gen 1 · 1 GHz operating frequency target on PCIe Gen 6. CHI Rev E.b coherency without latency compromise.

OA

Optimal Area

Modular, reusable microarchitecture eliminates redundancy across IP instances. ATC, ATS, and DTI shared between PCIe Gen 6 and CXL 3.0 subsystems: one NoC attachment point for two protocols.

Motion 2: Chiplet design

Your spec.
Our integrated IPs.
One tape-out-ready silicon.

Compute, IO, and Memory Expander silicons are not off-the-shelf products: they're custom design engagements. You bring the architecture requirements. SignatureIP assembles the right IP blocks, integrates them to your spec, and delivers a sign-off-ready silicon.

iNoCulator™ design tool

Design your NoC in the browser.

The only cloud-native NoC EDA tool. Set your targets. The tool designs the topology and generates the optimal C-Noc and NC-NOC topology generation. Configures for single-silicon monolithic SoCs and multi-silicon chiplet packages: the same tool serves both design motions.

  • Full sign-off flow. RTL feeds directly into Siemens Questa simulation.
  • Processor-agnostic. Arm CHI, RISC-V, and custom processor interfaces.
