About the NetStream-Caravel PCB

NetStream-Caravel is an open source FPGA PCB design by adulu-bang, published on GitHub under the Apache-2.0 license. It is a board, with 192 components from 41 distinct parts.

Its main chip is the XC7A100T-1CSG324C, from the FPGA family. Other key parts include the KSZ9031RNXCA, W25Q128JVS, TPS54620RGYR, TPS54302 and ASDMB-xxxMHz. By type, the board carries 93 capacitors, 75 resistors, 11 ICs, 6 inductors, 4 connectors and 1 transistor.

From the project

NetStream: a lightweight programmable packet-processing SoC with CPU control plane and TCAM-based dataplane (parser -- match -- action), implemented on the Caravel open-source ASIC platform for edge networking.

To demonstrate deployment feasibility beyond standalone ASIC implementation, a system-level PCB integration architecture was developed for NetStream. It is being implemented on KiCAD.

NetStream-Caravel: common questions

What microcontroller does the NetStream-Caravel use?

The NetStream-Caravel is built around the XC7A100T-1CSG324C, from the FPGA family.

How many components are on the NetStream-Caravel?

192 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the NetStream-Caravel design files?

From the adulu-bang/NetStream-Caravel repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the NetStream-Caravel design in my own project?

Yes, under the terms of its Apache-2.0 license, which adulu-bang chose for the repository.

Can I test firmware for the NetStream-Caravel without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
