PROFILE
Maxim Kudinov
Max Kudinov contributed to the YosysHQ/yosys repository by developing and enhancing FPGA synthesis features, focusing on Gowin device support. He implemented new synthesis logic in C++ and Verilog to enable multiplication inference and DSP mapping for GW1N and GW2A families, broadening device compatibility and improving resource utilization. Max introduced configurable command-line options, such as -setundef and -nodsp, to increase safety and flexibility in the synthesis flow. His work included refining documentation, improving CLI usability, and expanding test coverage for DSP inference. These contributions deepened the reliability and maintainability of the Yosys synthesis flow for embedded and digital design.

Feb 1, 2026February 2026 monthly summary for YosysHQ/yosys focused on delivering Gowin DSP inference enhancements and improving the Gowin synthesis flow. Key changes reduce configuration friction and improve test coverage, enabling more predictable DSP-aware synthesis for Gowin targets. Key features delivered: - Gowin DSP inference controls and synthesis improvements: merges label handling in SynthGowinPass to streamline the Gowin synthesis flow, adds a new -nodsp CLI option to disable DSP multiplier inference for flexibility, and adds tests to verify DSP inference behavior across configurations. Includes minor formatting improvements to Gowin-related code for readability. Major bugs fixed: - No major bugs fixed this period. Overall impact and accomplishments: - Improves configurability and reliability of Gowin DSP synthesis, enabling faster experimentation and more predictable builds. Expanded test coverage reduces regression risk and supports future DSP-aware optimizations. Technologies/skills demonstrated: - Code changes in the Gowin flow (C++/Verilog-related components in Yosys) with CLI flag development (-nodsp). - Test-driven development with DSP inference tests across configurations. - Readability and maintainability improvements through code formatting.
