Description of Business	Description of Business Synopsys, Inc. (Synopsys, we, our or us) is the leader in engineering solutions from silicon to systems, enabling customers to rapidly innovate AI-powered products. We deliver trusted and comprehensive solutions spanning silicon design, silicon intellectual property (IP), simulation and analysis (S&A) as well as design services. We partner closely with our customers across a wide range of industries to maximize their R&D capability and productivity, powering innovation today that ignites the ingenuity of tomorrow. We are a global leader in supplying the mission-critical EDA software that engineers use to design and test integrated circuits (ICs), also known as chips or silicon, and we are pioneering artificial intelligence (AI) driven chip design across the full-stack EDA suite to improve efficiency and accelerate the design, verification testing and manufacturing of advanced digital and analog chips. We provide software and hardware used to validate the electronic systems that incorporate chips and the software that runs on them, including cloud-based digital design flow to boost chip-design development productivity. We also provide technical services and support to help our customers develop advanced chips and electronic systems. Following the completion of the Ansys Merger (as defined below), we are the global leader in engineering S&A software. Our Ansys® solutions portfolio is widely used by engineers, designers, researchers and students across a broad spectrum of industries and academia, including high-tech, aerospace and defense, automotive, energy, industrial equipment, materials and chemicals, consumer products, healthcare and construction. These products enable customers to analyze designs on-premises and/or via the cloud, providing a common platform for fast, efficient and cost-conscious product development, from design concept to final-stage testing, validation and deployment. These products and services are part of our Design Automation segment. We also offer a broad and comprehensive portfolio of semiconductor IP solutions, which are pre-designed circuits that engineers use as components of larger chip designs to reduce integration risk and speed time to market. Our high quality, silicon-proven semiconductor IP includes logic libraries, embedded memories, analog IP, wired and wireless interface IP, security IP, embedded processors and subsystems. To accelerate IP integration and silicon bring-up, our IP Accelerated initiative provides architecture design expertise, hardening, and signal and power integrity analysis. These products and services are part of our Design IP segment.
