Min Experience: 2+ years Location: Hyderabad, Telangana, India JobType: full-time
We are seeking an experienced Memory Circuit Design Verification Engineer to verify and validate complex memory circuits, memory IP, and full-chip memory designs. The ideal candidate will have a strong understanding of memory architectures, circuit-level simulation, digital verification, and timing analysis, with hands-on experience in pre-silicon verification and debugging.
In this role, you will develop and execute verification strategies, perform SPICE/FastSPICE and gate-level simulations, analyze critical memory timing parameters, and validate design robustness across process, voltage, and temperature (PVT) conditions. You will collaborate closely with memory designers, circuit engineers, characterization specialists, and design verification teams to identify design issues, improve verification methodologies, and ensure functional correctness and timing compliance.
Requirements
Key Responsibilities
- Memory Circuit Verification: Perform block-level and full-chip verification of memory circuits, memory IP, and associated design components.
- Verification Planning: Develop and execute verification plans, test cases, test vectors, testbenches, and simulation regressions to validate design functionality.
- Circuit Simulation: Run SPICE and FastSPICE simulations to verify circuit behavior, memory operations, and critical timing parameters.
- Gate-Level Verification: Execute gate-level simulations with timing delays and analyze logic schematics to identify functional and timing-related issues.
- Memory Timing Analysis: Evaluate read/write operations, setup and hold times, access time, critical data paths, timing margins, and other memory timing characteristics.
- Memory Architecture Validation: Verify memory architectures such as SRAM, DRAM, DDR, LPDDR, and emerging memory technologies based on project requirements.
- Debugging and Root-Cause Analysis: Investigate functional failures, waveform mismatches, timing violations, and circuit-level issues, collaborating with design teams to implement corrective actions.
- PVT and Corner Analysis: Validate design performance and reliability across process corners, voltage variations, temperature conditions, and speed grades.
- Verification Environment Development: Build, maintain, and enhance testbenches, verification environments, automation scripts, and regression frameworks.
- Regression and Coverage Analysis: Analyze simulation results, improve functional coverage, identify verification gaps, and optimize regression efficiency.
- Design Collaboration: Work with memory circuit designers and cross-functional engineering teams to resolve design issues and improve overall design quality.
- Verification Sign-Off: Support pre-silicon verification sign-off, maintain technical documentation, and communicate verification results and unresolved risks.
