`Constellation <https://github.com/ucb-bar/constellation>`__ is a Chisel NoC RTL generator framework designed from the ground up to support integration in a heterogeneous SoC and evaluation of highly irregular NoC architectures.
|
|
|
|
- Constellation generates **packet-switched wormhole-routed networks with virtual networks and credit-based flow control**
|
|
- Constellation supports **arbitrary directed graph network topologies**, including **irregular** and **hierarchical** network topologies
|
|
- Constellation includes a **routing algorithm verifier and routing-table compiler**, which can verify and generate deadlock-free routing tables for arbitrary topologies
|
|
- Constellation is a **protocol-independent transport layer**, yet is capable of compliant deadlock-free transport of protocols like **AXI-4** and **TileLink**
|
|
- Constellation supports drop-in **integration in Chipyard/Rocketchip SoCs**
|
|
- Constellation is **rigorously tested**, with almost 100 different tests across as many network configurations
|
|
|
|
Constellation is fully integrated into Chipyard, and can be used to generate almost any interconnect in a Chipyard/Rocketchip-based SoC.
