The Terabit Ethernet card is designed and suitable for filtering TCP packets on optical fiber.
Malicious packets can be dropped, and packets carrying selected protocols or data can be picked and forwarded for further processing.
Target customers include ISP data centers, cloud services, and stock trading companies.
Consilia was requested to create a layout for this 400 Gbps PCIe card. The component density was reaching the physical limits of the manufacturing process.
Thermal management posed a significant challenge due to the excessive power dissipation of the packet processing FPGA.
The first challenge was the selection of the proper stack-up and the PCB manufacturer. There are only a few manufacturers in the world that have and can process materials designed for this kind of card.
The placement of the components was an input for the thermal management system team that started thermal simulations.From then on, the thermal management system team and the layout team cooperated closely. The Development teams discussed the change of placement of each component from the point of view of signal integrity and thermal management.
When the board was finished, a DFM (Design for Manufacturing) analysis was conducted at the selected assembly house to ensure that the cards could be manufactured and assembled at the target line.
The card can be programmed in P4 – a high-level programming language optimized for packet forwarding. The packets can be inspected in real time at a full speed of 400 Gbps and thrown away immediately if detected as malicious.
Consilia provides turnkey solutions for PCB layout of any complexity ranging from 2-layer automotive PCBs up to xx-layer high-speed telecom cards and backplanes touching manufacturing limits.
The critical parameters of the board are PCB with 18-layer stack-up, high-speed differential pairs, blind/buried and stacked vias/µvias, back-drilling, FPGA chip with 3000 pins, and over 1800 components on PCB.
For cooling, a highly efficient copper profile cooler is specially designed for externally provided airflow, with efficient cooling of up to 100A power consumption.
Our client operates and develops the national e-infrastructure for science, research, and education which encompasses a computer network, computational grids, data storage, and a collaborative environment. The client offers a rich set of services to connected organizations.
We designed the PCB in the year 2021. Currently, we are working on a new innovative variant.
Since the foundation of Consilia in 2004, we have finished and supported dozens of projects.
Our team has been making advanced FPGA designs for more than 20 years. We implement designs for the chips produced by the top FPGA manufacturer brands, like Intel, AMD, and Lattice.
This is a crucial activity we do in the complete product creation or as an on-demand service. We can support you with our considerable experience and technical background, including circuit design know-how, manufacturing services, and a professional PCB layout team.
We can offer you our competence in designing automation systems based on our long-term expertise. Our know-how is deepened by developing new generation PLCs or developing industrial test cards.
We have always focused intensely on making our products interconnected and finding the best balance between autonomous and centralized approaches for the systems.
