Context

Advanced HBM-GPUintegration is a key enabler for next-generation AI systems, yet thermalconstraints remain a primary limiter. imec has recently demonstratedsystem-technology co-optimization approaches to mitigate thermal bottlenecks inadvanced HBM-GPU concepts under realistic power conditions.

However,early-stage design decisions are still often dominated by expensive, slowiteration cycles. There is a strong need for fast, data-driven screeningmethodologies that can translate power dissipation signatures into actionableguidance on which integration solutions should be prioritized for detailedanalysis.

Objective

Develop a portablemethodology and prototype toolchain that leverages power-map analytics toenable early-stage screening and prioritization of candidate advancedintegration solutions. The internship focuses on building robust,architecture-consistent power-map descriptors and a scoring workflow thatsupports design-space exploration under limited information.

Keyresponsibilities

Power-mapprocessing pipeline (Python-first)

Builda reproducible pipeline to ingest, normalize, re-bin, and analyzeworkload-derived power maps; support multiple map formats and resolutions.

Featureengineering for power-map "fingerprints"

Defineand implement multi-scale spatial descriptors capturing power concentration,heterogeneity, clustering behavior, and structural regularities in a way thatis robust across workloads and mapping conventions.

Architecture-consistentsynthetic power-map generation

Createsynthetic power-map variants that remain consistent with computer-architecturerealities (e.g., clustered activity, compute/memory locality, floorplanconstraints), to stress-test methodology robustness and generalization.

Screeningscore and decision workflow

Proposea scoring framework that can rank candidate integration solutions usingpower-map fingerprints and limited configuration metadata, with emphasis onstability, interpretability, and sensitivity analysis.

Validationand reporting

Validatethe screening workflow against a small set of reference cases and produce aconcise report summarizing methodology, robustness, and recommended usageboundaries.

Optionalstretch goal

Exploregenerative data augmentation (e.g., GAN-style synthesis) to enrich the space ofarchitecture-consistent power maps for robustness testing (kept optional andscoped to feasibility).

Candidateprofile

MScor early PhD student in Electrical/Computer Engineering, Computer Architecture,or related fields.

Stronghands-on programming skills; Python required (NumPy/Pandas; bonus:SciPy/scikit-learn).

Solidunderstanding of computer architecture and workload behavior (powerdistribution drivers, compute/memory interaction).

Comfortablewith building end-to-end research prototypes: data processing, metrics design,benchmarking, and clear documentation.

Interestin thermal/power topics and advanced packaging is a plus, but the internship isprimarily methodology- and tooling-driven.

Whatyou will deliver

Aclean and reproducible Python toolchain for power-map analytics and screening.

Adocumented set of power-map fingerprints and a screening score.

Ashort technical report including robustness analysis and recommended bestpractices for using the methodology in early-stage exploration.

Environment:

Youwill work in imec's highly interdisciplinary research environment, at theintersection of system technology co-optimization (STCO), power and thermalmodeling, memory and architecture research, and EDA methodology development.

Theinternship is embedded in imec's XTCO program thermal pillar, where architectural, physical,and system-level considerations are jointly explored to address next-generationcompute challenges.

Youwill collaborate closely with researchers across power/thermal modeling, memoryintegration, system architecture, and EDA tooling, and gain exposure torealistic industrial design constraints, data, and workflows. The work ishands-on and methodology-driven, with a strong emphasis on building reusableanalysis pipelines rather than isolated simulations.
