www.cadence.com 2 Cadence Schematic Capture add the connection —all automatically and quickly. Context-sensitive menus, OLE support, custom colorization of wires/nets/parts, and a tabbed/dockable interface all provide a better user experience. Project management The project manager (see Figure 1) enables users to collect and organize all the resources needed for the project throughout the design flow. The expanding tree structure makes it easy to organize and navigate design files, including those generated by Cadence PSpice ® and Allegro AMS Simulators, OrCAD Capture CIS, Allegro Design Entry CIS, and other plugins. The project manager offers easy navigation of design files. It also includes a wizard to guide users for specific design flows and a hierarchy viewer to display hierarchical relationships among design modules. Hierarchical design and reuse The full-featured schematic editor (see Figure 1) enables users to place and connect parts from a comprehensive set of functional libraries. It uniquely packages the parts, ensures design integrity, and creates design netlists for any of the formats supported by Cadence. Users can view and edit multiple schematic designs in a single session, and copy and paste design data between schematics, enabling data reuse. The schematic editor also supports the addition of critical constraints for a design editing to PCB editing flow. Libraries and part editing The library editor is accessed directly from the user interface. Users can create and edit parts in the library or directly from the schematic page without inter- rupting workflow. Intuitive graphical controls speed schematic part creation and editing. New parts can be created quickly by modifying existing ones. New parts can also be created from spread- sheets. A library part generator automates the integration of FPGAs and PLDs into the system schematic. The generate part feature simplifies the creation of core FPGA library parts for high pin-count devices. These parts can be split into multiple parts. Easy data entry Designers can access all part, net, pin, and title block properties or any subset and make changes quickly through the spread-sheet property editor (see Figure 1). It simply requires selecting a circuit element, a grouped area, or an entire page, and then editing part, net, or pin properties. Component information system Allegro Design Entry CIS and OrCAD Capture CIS integrate the features of a Component Information System (CIS) with Cadence schematic capture technology. The products are designed to reduce production delays and cost overruns through efficient management of compo- nents. The time spent searching existing parts for reuse, manually entering part information content, and maintaining component data is reduced. Users search for parts based on their electrical charac- teristics and CIS automatically retrieves the associated part (see Figure 2). CIS is ideal for individual design teams or teams who need to collaborate across multiple locations. It gives designers access to correct part data early in the design process and enables complete component specifications to be passed to board designers and other members of the design team, reducing the chances for downstream errors. It also provides access to cost information so designers can use preferred, lower-cost, and in-stock parts. The embedded part selector accesses information stored in MRP or ERP systems and engineering databases, and it synchronizes externally sourced data with the schematic design database so BOMs can be generated automatically Relational data support CIS allows for the creation and usage of relational tables in the component parts database. These relational tables have a one-to-many relationship with the part information (primary) tables. The relational database may contain a vendor table with multiple vendor/manufacture part numbers for a single company part number in the electrical (e.g. resistor) table. With this structure, search and query for data across the primary and relational tables is possible. Extended CIS documentation CIS also provides powerful report gener- ation. Instead of limiting designers to just those properties that reside in the schematic, CIS draws from the extensive wealth of information that resides in the preferred part database, taking report generation to the next level.
