Elements Generated by Import Tools

All import tools generate the following elements:

• The 5x library structure – The library, cell, and view structure is generated to import the netlist file of the design, for example verilog.v, into the Virtuoso Studio Design Environment environment without the need to launch Virtuoso.
• A symbol view of the specified cell – The symbol representation of the cell interface can then be instantiated as a place master in a schematic.
• A shadow database of netlist files – These tools save OpenAccess connectivity information in the netlist.oa file. Shadow-based netlisters need the netlist.oa file to ensure that the same connectivity information exists in the place master and the switch master.
• A schematic view – These tools generate a schematic view of the design.
  
  cdsTextTo5x does not support creation of schematic views.
• A blackbox of a cell – These tools optionally allow importing only the interface information of a design cell while ignoring the instance information. This improves the temporal performance when you import large designs.
• A single cell – These tools allow importing a specific cell or set of cells from a netlist file. This functionality eliminates the need to import the complete netlist.

Most import tools generate schematics, symbols, and the OpenAccess database. The exception is cdsTextTo5x, which generates only symbols and the OpenAccess database.
