Building Composable Chiplets
Today I had the pleasure of giving a talk at the CHISIC (Chiplets Solutions for Custom IC Design) workshop in Boston. CHISIC focuses on providing insights and solutions related to chiplet technology and its application in custom IC design, specifically targeting the field of artificial intelligence. The workshop aims to help attendees learn about the latest advancements in chiplet architectures, connectivity, and associated design challenges.
Talk Abstract:
Chiplets present a compelling approach to reducing the cost and time of chip design by raising the abstraction level to the die. In this talk, I will share my decade-long experience with chiplets and examine the current challenges blocking effective chiplet-based design for startups, government, and academia. Additionally, I will introduce recent work on composable (“interchangeable”) chiplets, where O(M^N) unique silicon systems can be assembled from N chiplets arbitrarily selected from a library of size M. To illustrate the potential of this approach, consider a 10 chiplet system built from a library of 10 chiplets, enabling the creation of 10⁹ unique configurations. In contrast, fewer than 10³ unique chip tape-outs occur worldwide each year. Standing up a practical composable chiplet platform on par with the existing SoC design ecosystem will require enormous investments, but if done right has the potential of fundamentally disrupting the semiconductor industry.
