You need to create these versions when: ■ You need different graphical representations as shown in above example. ■ You need scalable symbols. Different versions or symbol views are stored under directories named sym_1, sym_2, and so on. The symbol views of a part are created by using Part Developer: Part Developer lets you edit the schematic symbols, physical pin data, and part table data and create simulation views for multiple parts - all within a single user interface. Part Developer provides the ability to import part information from a variety of input sources, such as EDAXML and Si2PinPak, to create or modify Design Entry HDL and Capture parts, and to export part data in EDA XML and Capture format. Also, with built-in error checking, Part Developer ensures that symbols are consistent and error-free. Package View or Chips View The package view or the chip view stores the package information like pin names and electrical information for the part. This view connects the logical view of a component to its physical view. The pin information like pin names, types, loading and physical numbers is stored in the chips.prt file located in chips directory. Part Table View The part table view has additional physical part information that can be used to customize a part and is located in ptf directory. This view is used along with the package view or the chips view while packaging the part. Simulation View You can also associate a Verilog or VHDL module with each part used in a design and simulate the entire design using Cadence Simulation products. The simulation view contains all files required for simulating the part.
