The Netlist Out function is used to write out the routing information from the current data file to disk in the form of a netlist. The file will be scanned for un-named signals and sequential numbers will be assigned to those signals.
When you select this function, a dialog box will appear for the entry of the desired destination netlist file name. The default file name is the same as the source file with a .NET suffix. If the source file name contains a numeric suffix (such as .SH1), that number will be preserved in the output file suffix (i.e. .SH1 to .NT1).
