We are a couple of RTL design engineers with combined more than 40 years of experience in ASIC and FPGA digital design. We successfully led several chips through the whole process from feature define, RTL design, verification, to backend/DFT support, TO, and bring-up. We are familiar with Xilinx FPGA design too and have experience in using multiple FPGAs to verify complicated ASIC RTL design or for the final product. We are interested in working as independent contractor for your projects. Please send us private message if there is a match. Thank you!
