Special Session 4: Chiplet-based Integrated Systems

Introduction and Topics

Chip vendors face significant challenges with the continued slowing down of Moore's Law and the end of Dennard scaling which increases the time between new technology nodes and thus skyrockets manufacturing costs for silicon. The slowing down of Moore's Law makes it increasingly difficult to integrate more transistors on a single chip. If transistor sizes stay constant, more transistors could be integrated via larger chips. However, larger chips are undesirable due to significantly higher manufacturing and verification costs. Manufacturing defects in high density integrated circuits can dramatically reduce the wafer yield. Lower yield translates into higher manufacturing cost.

As a promising design paradigm to solve the above challenge, in chiplet-based systems, multiple die/chiplets are integrated within the same package via advanced packaging technology such as a multi-chip module or silicon interposer. The chiplet architectures provide a variety of benefits that make them attractive, including lower cost, higher flexibility, and better sustainability. However, the design methodology should be studied to support efficient design of chiplet-based systems. In this special session, we will focus on the challenges of chiplet-based integrated systems and innovations to address these challenges.

Topics for this session include but not limited to:

  • Advanced Packaging Technology
  • Die-to-die Interface & Interconnect Technology
  • Inter-Die Communication Network
  • Chiplet-based Accelerator Design
  • Chiplet-based Heterogeneous Systems
  • Architecture & Design Space Exploration for Chiplet-based Systems
  • EDA tools for Chiplet-based Systems
  • Reliability, Testing, and Security for Chiplet-based Systems
  • Physical Design for Chiplet-based Systems
