Siemens, through its acquisition of Mentor Graphics, offers a range of powerful EDA tools for VLSI and SoC design. Some of Siemens' key tools include:
Detailed Explanation
Siemens has expanded its capabilities in the Electronic Design Automation industry by acquiring Mentor Graphics, which was known for its strong EDA tools. The result is a portfolio of innovative tools designed to support complex designs like Very Large Scale Integration (VLSI) and System-on-Chip (SoC). These tools are critical for ensuring that designs are efficient, meet specifications, and are ready for manufacture.
Examples & Analogies
Think of Siemensβ acquisition like a company purchasing a successful restaurant chain. Just as the new owner benefits from the existing popular recipes and management practices, Siemens can leverage Mentor Graphicsβ established tools and expertise to enhance their toolkit in EDA.
Calibre

β Calibre: Calibre is a leading physical verification tool for DRC (Design Rule Checking), LVS (Layout Versus Schematic), and ERC (Electrical Rule Checking). It ensures that the design meets manufacturing process constraints and that the physical layout corresponds to the intended schematic.
Detailed Explanation
Calibre serves as a quality control mechanism in EDA design processes. It checks whether the design adheres to manufacturing rules (DRC), verifies that the layout matches the schematic (LVS), and assesses electrical integrity (ERC). These checks are essential to prevent costly errors in the manufacturing phase and ensure that the design will function as intended once produced.
Examples & Analogies
Imagine a builder using strict blueprints to construct a house. They check that every beam and wall aligns with the plans just as Calibre checks designs against a set of established rules to make sure they are buildable and functional.
Xpedition

β Xpedition: Xpedition is an advanced tool for PCB and IC package design. It integrates with other Siemens tools to offer a seamless workflow for design and simulation.
Detailed Explanation
Xpedition is focused on the physical layout of printed circuit boards (PCBs) and integrated circuit (IC) packaging. Its strength lies in its ability to connect with other Siemens EDA tools, allowing for a streamlined process from design through simulation. This integration is important for reducing the risk of errors and speeding up the design-to-manufacture timeline.
Examples & Analogies
Think of Xpedition like a conductor leading an orchestra. Just as a conductor coordinates the different instruments to create a harmonious performance, Xpedition helps bring together various design elements to ensure they work together efficiently and effectively.
