Circuit Design & Verification Engineer

Key Responsibilities

• Analyze and interpret transistor-level, gate-level, and memory circuit schematics to understand functionality, performance, and timing behavior.

• Perform circuit simulations using industry-standard SPICE simulators, including DC, transient, and timing analysis.

• Develop and validate building block and memory circuit designs through simulation, characterization, and correlation activities.

• Debug gate-level simulation failures and perform detailed root-cause analysis at both gate and transistor levels.

• Conduct what-if analysis and implement design modifications to validate corrective actions and optimize circuit performance.

• Work with latch-based and sequential logic designs, ensuring compliance with timing requirements and design constraints.

• Support timing characterization activities, including timing libraries, timing arcs, and associated file formats.

• Execute and analyze netlist simulations using Verilog MOS switch-level models, including zero-delay, unit-delay, and path-delay simulation methodologies.

• Correlate gate-level simulation results with SPICE simulations to ensure design accuracy and timing closure.

• Collaborate closely with design, verification, and architecture teams to resolve complex circuit and timing issues.

• Document findings and communicate technical concepts effectively to cross-functional engineering teams.

Required Qualifications

• Strong experience with transistor-level and gate-level circuit analysis and debugging.

• Hands-on expertise with SPICE simulation tools and circuit characterization methodologies.

• Solid understanding of memory architectures, latch-based designs, and timing verification.

• Experience with timing libraries, timing arcs, and characterization flows.

• Proficiency in Verilog switch-level modeling and gate-level simulation environments.

• Strong debugging skills with the ability to identify and resolve issues at both circuit and transistor levels.

• Excellent analytical, problem-solving, and communication skills.

Preferred Qualifications

• Experience with UVM-based verification environments.

• Familiarity with advanced timing validation and silicon correlation methodologies.

• Exposure to semiconductor design, verification, and post-silicon validation flows.
