PROFILE
Sai Ma
Masai developed and maintained the bedrock-rtl repository, focusing on robust RTL and formal verification infrastructure for FPGA and ASIC hardware designs. Over 11 months, Masai delivered features such as parameterized FIFO and arbiter modules, advanced AXI protocol verification, and assertion-based test automation, using SystemVerilog, Verilog, and Tcl scripting. Their work included expanding error correction code (ECC) coverage, optimizing build systems with Bazel, and stabilizing regression environments for continuous integration. By addressing both feature development and bug fixes, Masai improved test reliability, coverage, and maintainability, demonstrating depth in hardware verification and a methodical approach to scalable, production-ready digital logic design.
