User manual CADENCE DESIGN SYSTEMS VIRTUOSO LAYOUT SUITE L DATASHEET

[. . . ] In addition, custom circuits are more sensitive to physical effects, which are exacerbated at new nanometer process nodes. The new unified Virtuoso custom design platform utilizes the latest in modern user interfaces and design tool integration advances to bring unprecedented levels of productivity and integration to design creation, verification, and implementation. Backed by the largest number of process design kits (PDKs) available from the world's leading foundries--for process Cadence® Virtuoso® Layout Suite L is the base-level physical layout environment of the Virtuoso custom design platform, a complete solution for front-to-back custom analog, digital, RF, and mixed-signal design. [. . . ] Additional acceleration is provided through parameterized cells (Pcells) and SKILL, a proven and powerful scripting language that provides direct database access and tool configuration. FEATURES Hierarchical, multi-window, multi-tabbed, intuitive editing environment Virtuoso Layout Suite L enables users to open multiple cells or blocks in a single editing session, or different views of the same design, to more effectively edit large hierarchical designs. Users can also open and manage their designs more quickly by using tabs, bookmarks, and history. A tabbed approach to viewing layouts, similar to functionality in today's popular web browsers, simplifies window management and provides fast access to multiple designs in an intuitive manner. This is particularly helpful when copying portions of a layout from one design to another, or when using a pre-existing design as a reference. Figure 2: Docked layout assistants include a Design Navigator, Property Editor, and World View, which enhance layout productivity www. cadence. com VIR TUOSO LAYOUT SUITE L 2 This consistent use model enables a fully featured, intuitive, front-to-back design flow. for repetitive panning and zooming. This translates into fewer mouse clicks, which improves layout productivity. DOCKED LAYOUT ASSISTANTS Docked assistants are user interface widgets that surround the main layout editing canvas. Within Virtuoso Layout Suite L are a rich set of assistants includingaDesignNavigator, Property Editor, Search, and World View that enhance layout productivity. ThroughtheDesignNavigatorAssistant, users can quickly and efficiently access specific cells that may be in a lower level of the design hierarchy via a built-in tree browser. Cells, nets, and pins can also be selected, sorted, and probed through the DesignNavigator. Thisisaveryeffective feature when designing and debugging complex layouts. The Property Editor Assistant is a new twist on the traditional "Edit Properties" pop-up form. Its streamlined interface increases layout canvas space while decreasing mouse clicks and spaceconsuming pop-up dialog boxes. The Search Assistant provides layout engineers with comprehensive search capabilities. It categorizes the "found" items into logical groups (cells, pin names, properties, etc. ) and displays these items in a tree structure, making it easy for users to find and access information within the design, design libraries, menu commands, and even the SKILL programming language manuals. Context-sensitive menus and double-click operations allow for rapid operations on selected results. The World View Assistant is an intuitive navigational aide that allows users to always see the entire design even while zoomed-in to a specific section of layout. This is particularly useful when working with large layouts where users have to perform editing while zoomed-in on a portion of the design. Being able to concentrate on a specific section of layout, while still having the full layout context available, decreases the need FLEXIBLE PCELLS Parameterized cells (Pcells) provide an advanced level of design automation to minimize tedious and repetitive layout tasks. Pcells support the changing of the size, shape, or contents of each cell instance without changing the original cell. They raise the level of abstraction to the component level. [. . . ] SKILL-programmable Pcells are also interoperable with Qcells.
