Enabling SoC Developers to Create Physically Valid NoCs Faster

The world's #1 on-chip fabric is used by the world's top semiconductor design teams as the backbone on-chip communications for chips targeting the fastest growing markets.

The latest generation FlexNoC 5 Interconnect with its integrated physical awareness technology, gives place and route teams a much better starting point while simultaneously reducing interconnect area and power consumption. FlexNoC 5 delivers up to 5X shorter turn-around-time versus manual physical iterations.

The Most Complete
Network-On-Chip Product

Everything design teams need to create the world's best SoCs, faster

topologies icon

Flexible Topologies

FlexNoC is generated from simple elementary components which are combined by a powerful set of underlying algorithms and an intuitive GUI, making it possible to build any topology.

chips icon

Small to Large SoCs

FlexNoC easily supports long cross-chip paths by leveraging source-synchronous communications and virtual channels.

bandwidth icon

Huge Bandwidth

FlexNoC drives performant on-chip data flow and access to off-chip memory by enabling multi-channel HBM2 memory and high bandwidth data paths.

Sondrel has deployed Arteris FlexNoC interconnect IP across several customer SoC projects to great effect. Physical constraints have always been an important issue and are even more important below 16nm geometries. The latest FlexNoC 5 with its physical awareness technology, enables our RTL teams to verify that architectures meet physical constraints and provide a better starting point for our place and route team. We look forward to our continued cooperation with Arteris.
