Description

Introduction

Synopsys 3DIC Compiler is an advanced platform for multi-die and chiplet-based IC design. It supports 3D floorplanning, integration, and system-level analysis. Moreover, it enables engineers to analyze power, thermal, and interconnect behavior across stacked dies. Therefore, it is widely used in advanced heterogeneous system design. It also supports TSV-based and interposer-based architectures for modern 3D IC development.
