Senior Principal SWE - Accelerated Verification Ip

**At Cadence, we hire and develop leaders and innovators who want to make an impact on the world of technology.** ----------------------------------------------------------------------------------------------------------------- The AVIP (Accelerated Verification IP) and Virtual Bridge (VB) business is a core part of Cadence’s Virtual Emulation and System Verification portfolio, enabling high‑performance verification on Palladium and Protium platforms. The team builds **high‑performance protocol solutions** that enable customers to verify complex SoCs and systems at **much higher speed and scale** than traditional simulation. Together, AVIP and VB are critical to customers building **high‑performance compute, AI, networking, and memory‑coherent systems**, where early software bring‑up, performance analysis, and protocol compliance are essential. The **AVIP / Virtual Bridge R&D team** designs, implements, and productizes protocol solutions that span **hardware, software, and system‑level verification**. The team works across multiple layers, including: * Protocol architecture and feature definition * High‑performance transactor and BFM development * Hardware‑software co‑simulation and emulation flows * Debug, logging, performance profiling, and compliance features * Customer enablement, escalations, and interoperability validation The team supports a broad portfolio of **industry‑standard protocols**, such as PCIe, CXL, Ethernet, USB, UCIe, and emerging interconnects, and works closely with **emulation platform teams, controller/PHY teams, and customers**. This role will contribute directly to the **development and enhancement of PCIe/CXL AVIP and/or  PCIe/CXL Virtual Bridge products**, focusing on protocol functionality, performance, and robustness. Depending on the specific protocol area, the work may involve: * Implementing PCIe protocol features and state machines * Enhancing performance and scalability on emulation platforms * Developing debug, trace, and analysis capabilities * Supporting system‑level and software‑driven use cases via PCIe Virtual Bridge * Working with customers and field teams to resolve issues and deliver solutions related to PCIe and CXL In this role, the engineer will be responsible for **designing, developing, and maintaining PCIe/CXL AVIP/VB components** as part of a larger protocol solution. The role is hands‑on and spans **feature development, validation, and customer readiness**. ### Key responsibilities include: * Designing and implementing protocol functionality in PCIe AVIP and/or Virtual Bridge components * Developing and debugging BFMs, transactors, and associated software interfaces * Ensuring correctness, performance, and scalability in emulation and acceleration flows * Collaborating with cross‑functional teams * Participating in feature bring‑up, regression, and release activities * Supporting customer issues, reproducing problems, and delivering fixes **What you’ll need** * BS with a minimum of 10 years of experience OR MS with a minimum of 7 years of experience OR PhD with a minimum of 5 years of experience * Strong fundamentals in **digital design, computer architecture, and system‑level verification** * Experience with **hardware description languages (SystemVerilog/Verilog)** and/or **C/C++** * Understanding of **standard interconnect or IO protocols** (e.g., PCIe, CXL,  NVMe) * Familiarity with **emulation, acceleration, or hybrid verification flows** is a strong plus * Good debugging skills using waveforms, logs, and protocol analyzers * Ability to work across hardware and software boundaries _The annual salary range for California is $154,000 to $286,000. You may also be eligible to receive incentive compensation: bonus, equity, and benefits. Sales positions generally offer a competitive On Target Earnings (OTE) incentive compensation structure. Please note that the salary range is a guideline and compensation may vary based on factors such as qualifications, skill level, competencies and work location. Our benefits programs include: paid vacation and paid holidays, 401(k) plan with employer match, employee stock purchase plan, a variety of medical, dental and vision plan options, and more._ **We’re doing work that matters. Help us solve what others can’t.** -------------------------------------------------------------------
