A netlist for the current cell is loaded. Supported formats are: spice, structual VHDL, alliance, qucs, eagle, PADSpcb and OpenAccess. Support for other file format can be extended on request. The schematic component libraries or netlist import libraries are used to perform the import and link the devices of the loaded netlist to a layout. For each cell of a design three different netlist can be stored: one loaded netlist, a netlist generated from the SchematicEditor and an extracted netlist. Which netlist is displayed in the netlist dock can be choosen which in the dock.
