Job Description:

 

Responsibilities:

  • Architecting test methodologies applicable to a wide range of CPU designs for CPU memory sub-systems including memory virtualization (Paging and Hypervisors), LoadStore unit, various levels of caches and industry standard bus protocols (e.g., AMBA and Tilelink).
  • Creating effective verification strategies for CPU memory system caches.
  • Building test plans to implement these strategies, considering issues such as design feature priority, potential customer impact, coverage metrics generation and measurability, etc.
  • Developing tools, test benches, and test suites (UVM, C++/C or otherwise, as needed) to execute test plans.
  • Developing and using unit level test benches that use constrained random stimulus.
  • Using assembly code Random test generators to meet verification objectives in single and multi-core CPU environments.
  • Writing directed assembly tests as appropriate to test CPU functions.
  • Providing technical leadership to verification engineers and coordinating technical teams to execute our verification strategies to meet program goals.
  • Collaborating closely with the design team on feature specifications, test plans and failure analysis.

Requirements:

  • 10+ years of recent experience with standard verification tools and methodologies (C,UVM, Verdi/DVE, System Verilog, Verilog, Make files, scripting languages, etc.), especially in hands-on testbench development and test suite generation.
  • Solid understanding of CPU and SoC memory architecture including memory virtualization (hypervisor, paging), Load-Store unit, various levels of caches, cache coherence protocols, bus interface units, and memory controllers.
  • Experience with industry standard system bus protocols (e.g., CHI, ACE, AMBA AXI, AHB, APB) is preferred. Knowledge of Tilelink is a plus.
  • A thorough understanding of the high-level verification flow methodology (test plan generation, test generation, failure analysis, coverage analysis and closure).
  • Ability to effectively assess the design verification metrics, remaining state space to be covered, and efficient methods to achieve verification closure.
  • Verification experience in test planning, constrained random test generation, test stimulus, code coverage, functional coverage.
  • Ability to learn languages and methodologies that are not part of the industry standard to verification (Scala, Chisel, etc.)
  • Understanding of CPU memory systems caches from an architectural level
