• Gain exposure to industry-leading methodologies and contribute to breakthrough advancements in system modeling and advanced package design.
• Work in an environment that values continuous learning, creativity, and technical excellence.

What You'll Do:

System Modeling & Analysis

• Collaborate with Analog Engineers to develop and optimize UCIe and HBM architectures using MATLAB (SerDes, RF, Simulink, DSP, and Communications toolboxes).
• Develop and refine behavioral models for UCIe/HBM IP analog and digital blocks to enable system-level signal and power integrity analysis and IP architecture optimization.

Signal Impairments & Jitter Modeling

• Model and analyze critical signal impairments, including jitter (DCD, IQ, PSIJ, RJ) and block-level non-linearity.
• Develop system-level models for key circuit components such as Tx and Rx circuits, IO, FFE, pre-amplifiers, CTLE, PLLs, de-skew circuits, samplers, clock paths, and data paths.
• Implement advanced statistical modeling techniques, including:
  • Transfer function analysis, pulse response, impulse response, convolution
  • Probability density functions (PDF), cumulative density functions (CDF)
  • BER contour generation, bathtub plots, ISI, crosstalk, and jitter modelling

Model Validation & Methodology Development

• Validate and refine system models by correlating results with SPICE simulations and lab characterization data to ensure accuracy and reliability.
• Work closely with Analog Engineers to develop HSPICE testbenches that accurately capture analog block behavior.
• Continuously improve methodologies for jitter and non-linearity modeling, driving innovation and R&D in this domain.

Signal & Power Integrity (SI/PI) Expertise

• Apply deep expertise in SI/PI concepts across die-level, interposer, and package-level to drive comprehensive system analyses.
• Collaborate with the packaging team to design and model advanced package layouts, extract S-parameters using tools like HFSS, Raptor, and Clarity, and perform system-level SI/PI analysis.
• Work with the EMIR team for die-level PDN analysis, generating CPM models and performing system-level PI simulations to optimize power delivery across interposer, package, and PCB designs for UCIe and HBM architectures.
• You will report to the Principal Engineer.
