About the role
This role involves driving the verification of a cache-coherent interconnect subsystem in high-performance SoCs. It focuses on coherent interconnect and related subsystem behavior.
What you'll do
- Understand coherent interconnect architecture and create verification strategies and test plans.
- Develop and maintain verification environments, checkers, scoreboards, assertions, stimulus, and coverage models.
- Verify subsystem behavior across interface boundaries, protocol adaptation layers, and bridge paths.
- Define and execute directed and constrained-random tests to expose corner cases.
- Analyze failures, isolate root cause, and drive fixes across RTL, assertions, testbench infrastructure, and test content.
- Write functional coverage, analyze coverage results, and close coverage holes.
What you'll need
- Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
- 5+ years of relevant experience in IP, subsystem, or SoC functional verification.
- Strong hands-on experience with SystemVerilog and UVM-based verification.
- Solid understanding of cache-coherent systems, on-chip interconnects, and memory-subsystem behavior.
- Experience creating test plans, building testbenches, writing assertions, analyzing coverage, and debugging complex design issues.
- Experience verifying protocol behavior such as ordering, backpressure, buffering, arbitration, flow control, and error handling.
Nice to have
- Direct experience verifying coherent interconnect, NoC, cache, or memory-subsystem functionality.
- Experience with subsystem integration and protocol interactions across multiple interfaces or bridge paths.
- Familiarity with industry protocols such as AXI, CHI, ACE, CXL, UCIe.
- Familiarity with scripting and automation using Python or similar languages.
- Experience with formal verification, performance-oriented verification, or emulation / FPGA-assisted debug.
- Experience contributing reusable infrastructure or methodology improvements.
Skills: UVM-based verification, SystemVerilog, coherent interconnect, cache-coherent systems, coverage models
