Fidus Solution Portfolio

A client requested Fidus to integrate their proprietary technology into a unique product. Fidus was responsible for the full development, including electronic hardware design, FPGA coding, mechanical and thermal design, and embedded software architecture. Using a Xilinx Zynq Ultrascale+ MPSoC, the project included signal conditioning, clock recovery, FMC interface, signal conversion, optical QSFP communications, and PRBS-based error detection.

The embedded application ran on Linux hosted on the quad-core Arm Cortex-A53. Deliverables included bootloader/BSP, IP over PPP, support for various USB peripherals, and data gathering from a Cortex-M4 for ADC and sensor information. We provided a Yocto build environment and Jenkins automation for future builds. The project concluded on time, within budget, and with a cohesive embedded software solution.

This robust, conduction cooled HPC FMC card was designed to interface to a large variety of host cards. It provides multiple ADC channel inputs, clock generation and low jitter distribution, power regulation and post filtering. Utilizing our lab equipment, the analog front-end was parameterized and characterized. This product passes high-speed serial data to the FPGA host card utilizing JEDEC’s JESD204B serial standard for data converters; the Xilinx® JESD204B IP core was utilized.

Fidus’ client needed an offline power card to assess the quality and condition of the mains. Fidus delivered this solution, complete with modified BIOS parameters. This project required knowledge in power supply design, x86 processors, BIOS and BSP design, FPGAs, and DSPs.

We assisted the customer with a number of items, including a RoHS bill of materials scrub/redesign of this mostly analog board. All modifications were carefully identified, the associated risks were assessed, and the appropriate updates were made. Clear concise reporting and documentation was critical due to medical industry requirements.
