6 Harnessing the Power of HDL Coder and Collaborative Integration with NanoXplore

In the ever-evolving field of Field-Programmable Gate Array (FPGA) development, the synergy between advanced design tools and collaborative partnerships holds immense potential. This talk explores the transformative capabilities of HDL Coder, a powerful toolset for generating synthesizable HDL code from MATLAB and Simulink models, and its integration with NanoXplore, a leading provider of high-performance FPGA solutions.

The talk highlights the collaborative efforts between HDL Coder and NanoXplore, showcasing their combined expertise in FPGA architecture and design optimization. A specific use-case in space missions, focusing on satellites, demonstrates how this integration enables efficient implementation of complex functionalities while overcoming space, power, and reliability challenges. Attendees will gain insights into successful satellite missions leveraging this collaboration, resulting in improved performance, reduced development time, and increased reliability in space environments.

FPGA designers, algorithm developers, and system architects will learn how to leverage HDL Coder and NanoXplore for advanced space mission development.

7 Speeding up DO-178C Safety Certification with Trace-based Code Coverage

Collecting code coverage information is required for all the common software certification processes, including the one defined by DO-178C. This is usually a challenge because traditional code coverage measurement requires extensive code instrumentation which has all kinds of side effects like (additional) memory consumption, slowing down the execution, and much more. After discussing the overall added value of Lauterbach’s real-time-trace debug features for developers of any embedded application, this presentation explores the advantages of Trace-based Code Coverage for integration and system tests and demonstrates a practical example using an NG Ultra SoC by NanoXplore. We will observe and discuss the advantages of minimal or even zero code instrumentation used for Lauterbach’s new trace-based measurement method compared with the traditional source code instrumentation.

Speaker: Mr Ladislav Řehák (Lauterbach)

8 Star Dundee Contribution

SpaceFibre (ECSS-E-ST-50-11C) is an evolution of SpaceWire, being backwards compatible with SpaceWire at the packet level. SpaceFibre is a very high-performance, high-reliability and high-availability network technology specifically designed to meet the needs of modern space applications where very high throughput is required. It provides point-to-point and networked interconnections at Gigabit rates— more than 6.25 Gbit/s per lane for current FPGAs, with multi-lane allowing to reach up to 16 times the speed of a single lane —with Quality of Service (QoS) and Fault Detection, Isolation and Recovery (FDIR). SpaceFibre NORBY and OPS-SAT technology demonstrators have already flown SpaceFibre, with more missions in both Europe and the USA currently designing or planning to use SpaceFibre.

STAR-Dundee has developed a complete family of SpaceWire and SpaceFibre IP cores fully compliant with these ECSS standards.

A new generation of radiation-tolerant FPGAs is emerging to cope with the ever-growing processing power required by newer missions, the BRAVE FPGAs family is a good example of this new generation of FPGAs. SpaceFibre operation requires serial transceivers, which are already inbuilt in modern FPGAs. The SpaceFibre IPs have been adapted to take advantage of the specific transceivers and memory blocks offered by these new FPGAs.

In this work we present the effort done to ensure that STAR-Dundee SpaceFibre IP cores work on the BRAVE FPGAs including simulation results from the verification with simulation models of the transceivers, post-synthesis resource utilisation and simulation of SpaceFibre IP and hardware tests done in the process.

10 NEORV32 runs on NG-MEDIUM

Nanoxplorer’s Field Programmable Gate Arrays (FPGA) and tools, which help a user integrate their Register Transfer Level (RTL) projects in Nanoxplorer (NX) FPGA portfolio, matured to the point, where a user with few clicks in Graphical User Interface (GUI) Impulse or python environment (NxPython3) build their RTL code for BRAVE FPGAs. The main goal of our practice was to evaluate the latest NX tools and test them with a complex open-source RISC V core (NEORV32 RISC-V processor) and integrate NEORV32 on NgMedium BRAVE FPGA. NEORV32 RISC-V processor is a customizable microcontroller (System on Chip – SoC) with a 32-bit processor which supports all RISC-V instructions, and its RTL is written in VHDL and Verilog Hardware Description Language (HDL). The NEORV32 processor core bases on RISC-V instruction architecture, and a user can attach to the core various peripheries such as UART, SPI, WatchDog timer, etc. The synthesis and integration steps were given in the Python script and then run with NxPython3. After the tool successfully generated bitstream for NgMedium FPGA, we uploaded it on the NgMedium development board. As with any other processor running on an FPGA, evaluation and benchmarking of the NEORV32 synthesized version was with software (SW), which runs a robot spider with four legs, and each leg has three joints. The spider movements are given in the cartesian and polar coordinate system and then described in C language. After compiling C code, SW required 32kB of Memory. To fit the spider application in the NEORV32 processor, the processor consumed around 12% of logical/sequential components and 22 Block RAM for instruction and data memory. Implemented NEORV32 core runs with a clock frequency of 37.5MHz, which is sufficient for the program to execute periodically every 20ms.

11 RISC-V for payload Control and Data Processing

The FreNox RISC-V microcontroller IP has its heritage in numerous products for high-assurance and high-reliable security applications for data line encryption and network domain separation (i.e. NLD/EU/NATO-restricted). As a founding member of the RISC-V Foundation, Technolution has designed and implemented the FreNox RISC-V processor family. The FreNox RISC-V microcontroller IP has been integrated in numerous FPGA devices. We also ported the full AXI-4-based FreNox RISC-V system-on-chip into the radiation-hardened NanoXplore NG-Medium device, and have created a full interactive demonstration; through the SpW-interface we upload software in the RISC-V SoC, allowing the user to play the "Space Invaders" game on the NG-Medium board.

We keep improving our RISC-V platform; for instance with processor-agnostic simple gdb remote interface, implemented and demonstrated in the FreNox RISC-V processor. We have designed and implemented a simple gdb remote interface for multiple platforms to make gdb over a serial link a practical proposition for embedded microcontroller use. The implementation comes with limited hardware overhead, and has been included in our full interactive "Space Invaders" demonstration.

Under the Key Digital Technologies Joint Undertaking (KDT JU) TRISTAN project the RISC-V microcontroller design is being iterated for increased security and robustness for space application, such as implementing error and security checkers, lock-step operation, FDIR control and radiation testing.

For SmallSat payload control and data processing, we foresee wide use of reconfigurable FPGA technology. So, we have started the development of a novel payload control and data processing unit that is able to serve the evolving SmallSat market and is a perfect-fit solution for compact instrument developers. The proposed modular payload control and data processing architecture provides a good separation of concerns between instrument developers and platform provider allowing short time-to-orbit of payloads and missions. It offers a combination of FPGA-based instrument control functions, interface flexibility and powerful data processing capabilities. Telemetry and telecommand handling and most instrument control functions will be covered by our RISC-V softcore microcontroller.

13 Design Techniques for Multi-Core Neural Network Accelerators on Radiation-Hardened FPGAs

Radiation-Hardened-By-Design (RHBD) FPGAs have gained a lot of attention thanks to their excellent compromise between costs and performance. Being of very limited use due to a lack of performance a few years ago, these devices are now capable of implementing a wide range of applications requiring high computational capabilities.

This work describes an implementation of a Very Long Instruction Word (VLIW) soft-core convolutional accelerator in the NanoXplore RHBD NG-Medium chip. Feasibility and timing performances have been analyzed in order to discover whether and how multi-core solutions can affect parallel acceleration. Placement also showed to heavily affect the delays, up to 70% more, based on the proximity to the output buffers.
