The Opportunity:
UST is seeking a Simics Development Lead with extensive experience in pre-silicon virtual platform development. The ideal candidate will lead modeling and simulation of SoC/IP components using the Simics platform, collaborating with architecture, firmware, and validation teams to enable high-fidelity virtual prototypes.
Key Responsibilities:
· Lead the development of Simics-based models for SoC components, peripheral devices, and system-level interconnects
· Design and implement behavioral models to accurately represent pre-silicon hardware functionality
· Integrate custom models into the Simics simulation environment, validate model accuracy, and maintain model library
· Collaborate with architecture, design, firmware, and validation teams to capture modeling requirements and define deliverables
· Debug functional and performance issues in the models and support test execution teams using the virtual platform
· Drive improvements in simulation performance, fidelity, and reusability
· Document model interfaces, usage guidelines, and version changes
· Participate in code reviews, maintain code quality, and follow best practices for model development
Required Skills:
· Strong C/C++ programming skills with hands-on experience in modeling SoC/IP components
· Proficiency with Simics simulation environment or equivalent virtual platform tools (e.g., QEMU, SystemC)
· Deep understanding of SoC architecture, CPU/memory hierarchies, and peripheral interfaces (PCIe, I2C, SPI, etc.)
· Experience developing instruction-set simulators, transaction-level models, or behavioral models
· Familiarity with system boot flows and embedded firmware (UEFI, BIOS, BMC) •
· Working knowledge of version control systems like Git and build tools like Make/CMake
Desired Skills:
· Prior experience leading a modeling team or project
· Understanding of simulation performance optimization and debugging of race conditions
· Exposure to hardware design specs, register definitions, and firmware integration
· Experience with scripting languages (Python, Bash) for test and integration workflows
· Familiarity with CI/CD integration for model validation pipelines
Qualification:
· Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, or related field
· 4-7 years of experience in embedded software development, including 3+ years with Simics modeling or similar simulation environments
