Job Description:

This position for Senior Design Engineer - Modeling builds and runs the stand-alone testbenches, tests, regressions, and equivalence flows that independently validate the behavioral, functional, and architectural models and related collateral delivered by the Design Modeling team. The role ensures that delivered models, especially those used for user and software simulations, are functionally correct and equivalent to the actual hardware design.

The engineer works as part of the new Unit Testing team under the direction of the Design Modeling Manager and the Staff Design Engineer, and collaborates closely with IP Design, Design Verification, Integration, Software, Architecture, and Applications teams. The position supports validation of HLM, XML, and generated Chip Builder artifacts, enabling the senior modeling engineers to remain focused on customer commitments and delivery.

Key Responsibilities

• Develop stand-alone testbenches, directed and constrained-random tests, checkers, and scoreboards, in UVM or non-UVM format, to verify that functional and behavioral models match the actual hardware design.
• Build regression suites, coverage collection, and coverage dashboards, and support release qualification of HLM, IP XML, and generated Chip Builder artifacts against measurable release-exit criteria.
• Author, maintain, and execute test plans for assigned behavioral, functional, and architectural models, tracing each feature and behavior to tests and coverage points.
• Execute formal equivalency runs using Conformal XL or other industry tools for assigned custom IPs, covering cell behavioralized model versus schematic, and custom IP functional model versus full IP schematic. Set up mappings and constraints and debug non-equivalent points to root cause.
• Detect and triage RTL-model, schematic-model, primitive, XML, and configuration mismatches early in the development cycle, and work with model owners and design owners to drive them to closure.
