STA Engineer

## Company: Qualcomm Atheros, Inc. ## Job Area: Engineering Group, Engineering Group > ASICS Engineering General Summary: Qualcomm-Atheros, a.k.a. QCA http://www.qualcomm.com/qca/ is a wholly owned subsidiary of Qualcomm and a leading provider of wireless technologies for the mobile, networking, computing and consumer electronics markets. As a key member of a fast-paced Integrated Wireless Technology team. The role involves ownership and leading Static timing closure and synthesis for complex low-power WiFi SoCs and sub-systems. Responsibilities: Qualcomm’s Wi‑Fi SoC organization is seeking an experienced and highly skilled Static Timing Analysis (STA) and Synthesis Engineer to contribute to the development of next‑generation connectivity chipsets. This role focuses on driving timing‑critical implementation for high‑performance, low‑power Wi‑Fi solutions used across mobile, Access point (WIN), XR, automotive, and IoT platforms. You will collaborate closely with Architecture, RTL design, Design verification, DFT, and physical design teams to deliver high‑quality silicon on aggressive schedules. The responsibilities include the following * Timing Analysis: * Drive subsystem-level STA and timing closure for both pre-layout and post-layout phases, with support at full-chip level. * Perform timing analysis using PrimeTime (or equivalent tools) and contribute to full-chip signoff activities. * Identify timing bottlenecks, debug violations, and recommend micro-architectural or implementation-level optimizations. * Develop and validate SDC constraints, including Multi-mode and multi-corner (MMMC) setup, to enable accurate and efficient STA analysis. * Define and manage I/O timing budgets across hierarchical designs. * Provide actionable timing feedback at block/HM, sub-system and full-chip levels, including root cause analysis and ECO guidance. * Manage large-scale multi-corner/multi-mode STA runs with automation, partitioning, and efficient resource usage. * Collaborate with RTL, synthesis, and physical design teams to ensure robust timing closure. * Synthesis & Implementation: * Perform synthesis (including low power), formal verification (LEC), and low-power checks for complex SoCs, sub-systems, and cores. * Validate synthesis QoR and ensure clean handoff to physical design. * Develop, validate, and maintain SDC constraints. * Balance Power, Performance, and Area (PPA) constraints during implementation. * Perform functional ECOs including conformal ECOs * Methodology: * Develop AI‑driven flows using TCL, Perl, and Python scripts to automate and enhance efficiency across STA, synthesis, timing‑constraint development, ECO implementation, and low‑power verification flows. Required skill/experience * 6–8 years of experience in ASIC/SoC STA, synthesis (including low power), timing constraint development, Low power checks and functional ECO implementation. * Deep knowledge of Static Timing Analysis (STA), and timing constraints. * Experience with Multi Mode Multi Corner (MMMC) timing closure, OCV/AOCV/POCV, and advanced technology nodes. * Experience with timing closure sign off requirements. * Experience in Synthesis, Logical Equivalence Checking (LEC) (RTL-to-Netlist and Netlist-to-Netlist). * Understanding of SOC clocking and reset methodology and implementation. * Scripting skills in TCL and Perl. * Exposure to Low implementation techniques and design checks (multi-voltage designs, UPF). * Hands‑on experience with: * Synopsys Prime Time * Synopsys Design Compiler / Cadence Genus Preferred Qualifications * Implementation of Functional ECOs using Conformal ECO Tool. * Familiarity with Low power design, Bus implementation (AXI/AHB) and Clock Domain Crossing (CDC) * Exposure to physical design flows. * Scripting skills using Python. * Exposure to power estimation using PrimePower (PTPX) * Familiarity with Wi‑Fi, Bluetooth, or other wireless SoC design. *...
