Semidynamics is looking for an experienced FPGA Engineer to join our team and help push the boundaries of RISC-V prototyping and emulation. In this role, you'll integrate RTL releases into new FPGA designs, fine-tune peripheral configurations to maximize performance, and develop custom RTL modules that give our RISC-V cores the optimal I/O setup for emulation and prototyping. You'll work closely with cross-functional teams to translate their needs into robust FPGA solutions, help maintain and grow our in-house FPGA resource pool, and contribute to demonstration systems that showcase our technology to clients. Responsibilities: - Integrate RTL code releases into new FPGA designs; - Configure FPGA peripherals for maximizing the performance of the RISC-V prototyping solutions; - Implement new RTL modules to provide the RISC-V core under emulation/prototyping with the optimal I/O configurations; - Interact with other teams to understand their requirements for new features and on how that can be leveraged into the FPGA designs; - Maintain and further improve our in-house FPGA resource pool; - Provide support and develop new features to be used in demonstration systems for company clients. Requirements - 3+ years of industrial experience - Bachelor's or Master's Degree in Computer Engineering, Electronics or Telecommunications. - Experience working with Xilinx (or Altera) FPGAs using Xilinx Vivado (or Altera Quartus); - Proficient with HDL languages, preferably Verilog or SystemVerilog; - Work experience with scripting languages, preferably tcl and Bash; - Work experience with git version control; - Working in a Linux environment; - Knowledge of AXI4/AXI4-Lite, UART, I2C, SPI protocols; - Experience in using the Integrated Logic Analyser (ILA); - Experience in hardware debugging using laboratory equipment (multimeter, oscilloscopes, waveform generators, spectrum analysers). What will make you stand out: - Experience with timing constraints; - Knowledge on Xilinx Aurora, PCIe and Ethernet; - Knowledge of CHI protocol; Why Semidynamics? • Work at one of Europe’s most promising deep-tech semiconductor start up - from silicon to systems - Semidynamics. • Accelerated development path. • 4 days per week in the Barcelona office (city center), 1 day WFH. • 1 week of work from everywhere in the world. • Competitive package. • A collaborative, technical, and growth-oriented environment that values direct ownership and clear thinking.
