The OSFPGA Foundation aims to promote open-source FPGA tools and IP blocks

OSFPGA

There are been some initiatives to work on open-source tools for FPGA. Major FPGA vendors have made limited efforts, with for example Xilinx recently releasing the source code for HLS FPGA tool’s front-end, but most of the work is done by the community with projects like Symbiflow dubbed the GCC of FPGAs, or Project IceStorm for Lattice Semi FPGAs. Industry veterans and academics have decided to launch the Open-Source FPGA (OSFPGA) Foundation that aims to bring together companies, universities, and individuals to advance open-source FPGA capabilities, establish cooperation channels, promote outreach and education, and coordinate joint efforts around an open-source FPGA ecosystem. The OSFPGA Foundation goals go beyond just providing open-source tools, as the vision statement also mentions “open-source FPGA & eFPGA fabrics”, the Github page also includes IP blocks with the FuseSoC package manager for IP cores, the Skywater Open-source FPGAs, and LiteDRAM lightweight, configurable DRAM core. Current board members include: Dr. Naveed Sherwani, chairman of Silicon Federation. He […]

Xilinx open sources Vitis HLS FPGA tool (Front-end only)

Vitis HLS software architecture

While there are some open-source programs for FPGA development such as Symbiflow or Yosys, FPGA vendors usually only provide closed-source programs for developers wanting to work on their chips. But Xilinx has recently made a move to fulfill its “commitment to supporting open-source initiatives for developers and researchers” with the release of the source code of Vitis HLS Front-End. What is Vitis HLS exactly? Before we look at the source code release, we may want to know what Vitis HLS does exactly. The company describes it as a high-level synthesis (HLS) tool that allows C, C++, and OpenCL functions to become hardwired onto the device logic fabric and RAM/DSP blocks. It implements hardware kernels in the Vitis application acceleration development flow, and to use C/C++ code for developing RTL IP for FPGA designs in the company’s Vivado Design Suite. Vitis HLS design flow goes as follows: Compile, simulate, and debug the C/C++ algorithm. View reports to analyze and optimize the […]

CN0549 CBM development kit monitors assets through vibration analysis

CN0549 CBM Development Kit interfaced with SMA Connector

Condition Based Monitoring (CBM) has become quite popular in the manufacturing sector due to its advantages. It is a type of pre-analysis monitoring that includes the use of sensors to evaluate the status of an asset over time while it is in operation. Hence, the data collected is used to establish trends, predict failure, and measure the life of an asset. Analog Devices has launched CN0549, a condition-based monitoring development kit. The monitoring functionality signifies the consideration for hardware applications involving vibration. The applications include industrial as well as IoT devices. Hence, the CN0549 CBM development board combines the resources for a dynamic domain of users. Discussing further, condition-based monitoring (CBM) through vibration sensing requires the capturing of full-bandwidth data to ensure that all harmonics, aliasing, and other mechanical interactions are taken care of in both, the time and frequency domain. The data collection by using the sensors and data acquisition (DAQ) system offers high fidelity and real-time data analysis.  […]

Qomu Cortex-M4F & FPGA USB board is programmable with Symbiflow open-source toolchain (Crowdfunding)

qomu board

We’ve seen several tiny “omu” USB boards that are the size of a USB connector in the past, starting with Tomu based on Silabs EFM32 Arm-Cortex-M0+ MCU, then Fomu enabling Python programming and RISC-V softcore on a Lattice ICE40 FPGA, and finally Somu FIDO2 security key. There’s now the new Qomu board based on Quicklogic EOS S3 Cortex-M4F MCU with embedded FPGA. Just like its predecessor, the board almost completely fits in a USB connector except for the touch pads, and also happens to be programmable with Symbiflow that dubs itself as the “GCC of FPGAs”, as well as other open-source tools.
