Description

Introduction

Synopsys 3DIC Compiler is an advanced platform used for multi-die integration, 3D floorplanning, and chiplet-based system design. It helps designers build complex stacked architectures. Moreover, it optimizes interconnects and analyzes power, performance, and thermal behavior in heterogeneous 3D IC systems. The tool supports interposer-based designs, TSV planning, and die-to-die connectivity. Therefore, it is essential for modern advanced packaging workflows. In addition, it enables system-level planning, hierarchical design management, and early-stage feasibility analysis for 3D integration.
