    • Run generated RTL binaries on Palladium Z3 emulation.
    • Drive Joules gate-level power analysis.
  • Develop and maintain the Python, CSH, and Bash scripts that integrate and orchestrate the flow.
  • Add support for new AI network configurations, hardware accelerator variants, reference builds, and EDA tool revisions.
  • Maintain current documentation, patches, reference configurations, and reproducible build instructions.
  • Identify, debug, and resolve automation, infrastructure, and tool-integration issues across the workflow.

Performance and Power Collateral Generation

  • Generate complete performance and power collateral for each neural network processed through XNNC.
  • Collect and summarize:
    • Cycle count, frames per second (FPS), and memory-bandwidth metrics from XTSC simulation.
    • End-to-end performance metrics from Palladium emulation.
    • Dynamic power estimates, including total and memory power, from Joules gate-level analysis.
  • Deliver results consistently across reference builds in standard formats, including cycle-count CSVs, power CSVs, and consolidated summary reports.
  • Validate result quality, consistency, and reproducibility before collateral is shared with stakeholders.

Team Enablement and Support

  • Serve as the primary internal point of contact for users of the COLLATERAL-AUTO project.
  • Onboard new users and provide guidance on running the XNNC, Palladium, and Joules workflow.
  • Debug user runs and triage issues related to environments, scripts, CAD/EDA tools, and flow configuration.
  • Review performance and power summaries for correctness, completeness, and consistency.
  • Improve team-wide productivity by creating reusable guidance, troubleshooting documentation, and reliable reference workflows.

Technical Expertise

  • Strong Python scripting skills.
  • Proficiency with CSH and Bash shell scripting.
  • Working knowledge of JSON and automation-oriented configuration formats.
  • Understanding of hardware edge-AI accelerators, RTL execution flows, and performance analysis.
  • Familiarity with debugging complex software, toolchain, and multi-stage automation issues.

Education

  • Bachelor’s or Master’s degree in Software Engineering, Electronics Engineering, Electrical Engineering, Computer Engineering, or a related discipline.

Preferred Qualifications

  • Experience using AI-assisted development tools for rapid prototyping and effective technical prompting.
  • Experience with Cadence tools, including Palladium and Joules, or equivalent EDA/emulation/power-analysis workflows.
  • Familiarity with IP design platforms, RTL simulation or emulation, gate-level power analysis, and AI accelerator validation.
