Open hardware qualified Antmicro has introduced the launch of a new open source improvement board dependent all over the AMD Xilinx Kintex-7 K410T discipline-programmable gate array (FPGA) — hoping to see it adopted as a go-to prototyping platform for operate on open up silicon efforts.
“The AMD Xilinx Kintex-7 is a reasonably cheap and obtainable commodity FPGA relatives which makes it an exceptional prototyping and research system that is attainable to replicate at scale,” Antmicro clarifies. “As it transpires, for their default Earl Grey SoC [System on Chip] layout the OpenTitan undertaking has also been making use of a Kintex-7 K410T based mostly FPGA platform. The board is, on the other hand, a customized, proprietary style which is hard to arrive by or replicate.
“Since Antmicro is using OpenTitan as a template for extending the open up source SystemVerilog toolchain, to make it a lot easier reproduce the total style as-is (as an substitute to cutting it down to in good shape in extra approachable components) we built a adaptable open up components Kintex-7 K410T development board.”

That growth board, which unfortunately lacks a title extra interesting than the “Antmicro Kintex K410T Devboard,” pairs the 400k logic-cell AMD Xilinx FPGA with 512MB of DDR3L memory, 256MB of SPI NOR flash, and 8MB of static RAM (SRAM), with the option of two quad-SPI (QSPI) interfaces. You will find a gigabit Ethernet port together with a Quickly Ethernet port, an HDMI port for digital online video indicators, two PMOD connectors for insert-on components, an FPGA Mezzanine Card Plus (FMC+) connector for even more growth, and a USB Sort-C port which presents JTAG and serial debug capabilities.
For power, the board — which utilizes the nano-ITX structure — can acquire input from a DC barrel jack, the gigabit Ethernet port by using 40W Electrical power-over-Ethernet In addition-Plus (PoE++), or 45W USB Electricity supply (USB-PD) on the USB Sort-C connector. There are just one each individual of USB 2. Type-C and Type-A host ports, 8 indicator LEDs, and consumer-addressable DIP change and press-button inputs.

“The open components Kintex K410T progress offers a beneficial established of I/Os [Inputs/Outputs] valuable for a variety of ASIC [Application-Specific Integrated Circuit] prototyping scenarios,” Antmicro statements. “This features components-in-the-loop tests of patterns with many IP cores and peripherals, these kinds of as OpenTitan and variants thereof.
“The board’s FMC connector and dedicated adapters enable multi-channel info acquisition, generating it acceptable for rapidly-turnaround prototyping of multi-channel facts acquisition devices. The platform will also be helpful as component of the custom made runners CI infrastructure we have been acquiring for significant ASIC-relevant CI workloads.
