• Optimize data movement and memory access efficiency for high-performance computing and AI accelerator applications.

4. ASIC Development from Specification to Production

• Participate in the complete ASIC development lifecycle, from specification and microarchitecture through RTL design, verification, synthesis, physical implementation, tape-out, and silicon validation.
• Develop production-quality RTL that meets functional, performance, power, and area requirements.
• Collaborate with verification engineers on block-level and SoC-level verification plans, test cases, and functional coverage.
• Support lint, CDC/RDC analysis, formal verification, synthesis, static timing analysis, and design-for-test activities.
• Debug functional and timing issues identified during simulation, emulation, FPGA prototyping, and physical implementation.
• Support silicon bring-up, post-silicon debugging, performance characterization, and production validation.

5. Hardware/Software Co-Design and Verification

• Collaborate with firmware, driver, compiler, and system software engineers to define and implement hardware/software interfaces.
• Participate in hardware/software partitioning and optimization for AI accelerator applications.
• Develop register interfaces, control/status mechanisms, interrupt handling, and system-level data flows.
