Job Description

Circuit and Library Characterization: Standard Cell and SRAMExperience: 10+ YearsStrong expertise in characterization and modeling of standard cell libraries and SRAM macros across multiple PVT corners, ensuring accurate timing, power, and noise modeling for advanced technology nodes. Deep understanding of SRAM architectures including single-port, dual-port, two-port, pseudo dual-port, and multiport register file implementations, with the ability to interpret transistor-level designs and ensure accurate characterization coverage. Experience in characterizing SRAM sub-systems and peripheral circuits, including control logic, I/O latches, clock gating, row decoders, read/write assist circuits, sense amplifiers, clocking networks, tracking circuits, precharge/discharge paths, reset logic, and internal timing margins. Proficient in SRAM macro characterization and validation, including modeling of:Read/write timing arcsBit/byte write functionalityAssist and margin control circuitsAddress programmabilityRedundancy and repair mechanismsDFT features and test modesPower gating behaviorStrong experience in standard cell library characterization, including sequential and combinational cells such as latches, flip-flops, clock gating cells, adders, multipliers, and custom arithmetic blocks. Hands-on expertise in generating and validating complete timing, power, and noise models, including:NLDM/CCS timing and power modelsLVF (Liberty Variation Format) for statistical timing analysisInternal power and leakage characterizationState-dependent and multi-mode arcsEM/IR aware power modeling where applicableProven experience performing comprehensive Liberty QA and sign-off checks, including timing consistency, arc completeness, waveform integrity, and correlation with SPICE simulations. Strong ability to debug characterization issues, improve model accuracy, and ensure correlation between SPICE simulations, characterization outputs, and STA results. Experience developing and maintaining automated characterization flows and regression frameworks for large libraries and complex memory macros.EDA Tools and FlowsHands-on experience with industry-standard characterization and simulation tools including:Circuit Simulation & ExtractionCadence VirtuosoStarRC, QuantusHSPICE, PrimeSim XA, Spectre, PrimeSim CCKVariation, Modeling & AnalysisSolido HSVSpectre FMCNanoTimeLibrary CharacterizationLiberateLiberate MXSiliconSmartExperience in large-scale characterization automation, regression management, and library QA flows for standard cell and memory IP delivery.
