Inputs

The Mentor interface accepts netlists in EDIF or XNF format.

EDIF

You can submit an EDIF Level 2 0 0 netlist based on a design using Unified Libraries components. The following restrictions apply:

• Only the netlist and schematic types of EDIF are supported.
  
  
• Only one design per EDIF file is allowed.
  
  
• An EDIF file can contain one design component or multiple components. The EDIF2NGD utility converts each file to an NGO file. NGDBUILD uses a top-level NGO file, which refers to the other NGO files, to create the NGD file.
  
  

XNF

The Mentor interface can accept one of the following XNF netlists:

• An XNF netlist created by third-party netlist writers that meet the specifications of XNF version 6.1
  
  
• An XFF netlist created by XNFMerge version 6.1
  
  
• An XTF netlist created by XNFPrep version 6.1
  
  

An XNF netlist can represent all or part of a design. To be included in the netlist of a schematic design, a component must be tagged with the FILE property indicating the path name of the XNF file.

If a lower module is expressed in XNF, the top level must be run through EDIF2SIM in order to create a simulation netlist. The lower-level XNF file can not be run through XNF2SIM by itself since its lack of EXT records prevents XNF2SIM from knowing which signals should become module pins.
