Synopsys Design NDA Vx 2025.06 is not a standard software tool for design or simulation. It is a secure, confidential data package distributed under a Non-Disclosure Agreement (NDA) between a semiconductor foundry (e.g., TSMC, Samsung, GlobalFoundries), Synopsys, and the customer (a chip design company). This package contains the essential Process Design Kits (PDKs) and Reference Implementation Flows that enable customers to design integrated circuits for a specific, advanced foundry process node (e.g., 3nm, 5nm) using Synopsys EDA tools. It is the critical link that connects generic EDA software to the precise manufacturing requirements of a chosen silicon fab.

(H2) Core Components of a Design NDA Package

• Process Design Kits (PDKs)
  Includes the complete set of data required to design for a specific process: technology files (.tf), design rule files (.drf), parametric cells (P-Cells), and transistor-level simulation models (SPICE models). These are highly confidential and foundry-specific.

• Synopsys Reference Implementation Flows
  Provides pre-verified, step-by-step methodologies (scripts, configurations, and best practices) for using Synopsys tools (like Design Compiler, IC Compiler, PrimeTime) for the target process. This ensures designs meet the foundry's performance, power, and area (PPA) goals and signoff requirements.

• Foundry-Certified Digital & Analog/Mixed-Signal Flows
  Often includes separate, optimized flows for digital implementation and for custom/analog design (using tools like Custom Compiler), each tailored to the unique characteristics and design rules of the process node.

• Installation & Validation Documentation
  Contains instructions for installing the PDK and flows, and data for validating that the entire tool and kit setup is functioning correctly before starting production design work.
