As an ASIC Digital Design Verification Engineer, you will work closely with other digital designers and physical designers to develop the next generation of mining ASIC. In particular, the challenges of chip/block simulation, emulation and verification are critical parts of this role.
Key Responsibilities

• Block- and Chip-Level Verification: Develop and execute comprehensive test plans for individual IP blocks and full-chip integrations.
• Gate-Level Simulation & Debug: Run gate-level simulations, analyze netlists, and diagnose timing or logic issues.
• Silicon Bring-Up & Lab Debug: Support bring-up activities in the lab, perform board-level bring-up, and troubleshoot silicon on hardware using oscilloscopes, logic analyzers, etc.
• Automation & Scripting: Create and maintain scripts to streamline verification flows (e.g., regression, coverage collection, and reporting).
• Cross-Functional Collaboration: Work closely with RTL designers, physical design, firmware, and system teams to resolve issues quickly and efficiently.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field.
• 5+ years of hands-on experience in digital ASIC verification.
• Strong knowledge of verification methodologies, particularly UVM.
• Proficiency with EDA tools such as Synopsys VCS, Verdi, and waveform viewers.
• Solid experience with gate-level simulation.
• Experience with silicon bring-up and lab tools (oscilloscopes, logic analyzers, etc.).
• Proficiency in scripting languages (Python, Perl, Tcl, Make).
• Strong problem-solving and analytical skills with attention to detail.

Preferred Qualifications

• Master's degree in Electrical or Computer Engineering.
• Familiarity with serial interfaces such as UART
• Experience with common SoC IPs (PLL,GPIO etc)
• SystemVerilog RTL design experience.
• Exposure to full-chip emulation environments (e.g., Synopsys ZeBu).
• Hands-on experience with FPGA prototyping tools (e.g., Xilinx Vivado).
