Role description

SystemC Modeling Engineer

Specialist II - Semiconductor S/W Product Development

You Are:

We are looking for a skilled SystemC Modeling Developer to join our Server Architecture & Performance Engineering team. In this role, you will design and develop SystemC/TLM models for next-generation Compute and AI server platforms, enabling architecture exploration, performance analysis, and pre-silicon software development.

The opportunity:

• Develop SystemC/TLM
  2.0-based functional, timing, and performance models for server subsystems (CPU, memory, I/O, accelerators, AI engines).
• Build modular, scalable models for Compute & AI workloads and integrate them into simulation frameworks.
• Perform system-level performance modeling, profiling, and bottleneck analysis across compute, memory, and accelerator paths.
• Support pre-silicon BIOS, firmware, and driver enablement using virtual platforms.
• Validate models against RTL or hardware references to ensure functionality and accuracy.
• Work with simulators such as Synopsys Virtualizer, Cadence VSP, QEMU-based frameworks, etc.
• Collaborate with architects, RTL designers, platform engineers, and performance teams to align modeling results with product goals.
• Document model features, APIs, interfaces, and usage workflows for internal teams.

What you need:

• Strong hands-on experience with SystemC, TLM
  2.0, and C/C++.
• Solid understanding of computer architecture including CPU pipelines, cache hierarchy, memory controllers, PCIe/CXL, and AI/compute subsystems.
• Experience in cycle-accurate, timing-accurate, or transaction-level modeling.
• Knowledge of pre-silicon simulation flows and virtual platform development.
• Ability to analyze performance data, interpret system behavior, and provide optimization insights.
• Strong debugging skills in complex simulation environments.
• Desired
  
  Skills:
  
  Experience modeling AI/ML accelerators, GPUs, or heterogeneous compute units. Familiarity with server-class SoC architectures (x86, ARM, RISC-V).
• Exposure to firmware/BIOS bring-up using virtual models.
• Knowledge of RTL design (System Verilog) or hardware emulation (optional).
• Experience with performance tools, trace-driven analysis, or workload modeling.
• Understanding of high-speed interfaces (PCIe, CXL, NVMe, Ethernet).
• Qualification:
• Bachelor's or Master's degree in Computer Engineering, Electrical Engineering, Computer Science, or related field.
• 8+ years of experience in SystemC/TLM modeling, pre-silicon simulation, or architectural modeling for semiconductor/server platforms.
