In short

Synopsys is looking for a Senior R&D Engineer to characterize and model standard cell libraries for advanced technology nodes. This role involves generating various Liberty files, debugging correlation issues between characterization and STA, and driving methodology improvements. A Bachelor's or Master's degree in a related technical field and 2+ years of experience in library characterization are required.

Responsibilities

Characterize and model standard cell libraries for advanced technology nodes, generating Liberty files (NLDM, NLPM, CCS timing, CCS noise, ECSM, LVF, AOCV, POCV, spatial OCV, aging, and EM models).
Handle characterization across a wide range of cell types: combinational, sequential, clock gating, synchronizers, retention, level shifters, power gating, always-on, filler, and decap cells.
Debug and resolve correlation issues between characterization results, static timing analysis, and SPICE simulations, identifying root causes.
Execute QA checks, regression analysis, and release validation to ensure library deliverables meet quality and accuracy standards.
Drive methodology improvements and automation initiatives for characterization flows.
Coordinate project execution timelines, manage deliverables, and communicate status across cross-functional teams.
Support library releases by validating models against design rule checks and performing sanity testing.

Requirements

Bachelor's or Master's degree in Electronics, VLSI, Microelectronics, or a related technical field.
2+ years of hands-on experience in standard cell library characterization and Liberty modeling.
Strong understanding of Liberty file formats including NLDM, CCS, ECSM, and advanced modeling constructs like AOCV, POCV, and aging models.
Experience characterizing multiple cell types: combinational, sequential, clock gating, level shifters, retention, or power management cells.
Solid grasp of SPICE simulation, timing analysis concepts, and correlation methodologies between characterization tools and STA flows.
Proficiency in scripting languages like Python, Tcl, or Perl for automation, data analysis, and flow development.

Desired Qualifications

Experience with industry-standard characterization tools and STA platforms is a strong plus.

Benefits

Comprehensive medical and healthcare plans.
ETO and FTO Programs in addition to company holidays.
Maternity and paternity leave, parenting resources, adoption and surrogacy assistance.
ESPP with a 15% discount and 24-month look-back.
Retirement plans.
Competitive salaries.
