• Open Netlist
• Launch GofTrace
• Commands Menu
• Search Function
• Setup
• Change Fonts size short cut
• Create Waveform Restore File
• Design Statistic
• RTL Viewer
• Matching nets from RTL to Netlist
• List Fanin Fanout Endpoints
• Send marked lines to schematic
• Hyperlink for information fast access
• Driver and Load of Net
• Calculate area
• Diff utility

2. GofTrace: Partial incremental schematic creation from netlist. It draws only gates and connections that users have interest in.

• GofTrace Overview
• Trace fanin fanout
• Partial Schematic
• Save and Open Schematic
• List gate and load gate
• View options
• Annotate Schematic
• Zoom in Zoom out
• Search gates and nets
• Copy gates to
• SDF timing
• Place & Route
  • Auto Place & Route
  • Auto Place
  • Auto Route
  • Reset Route
• Layout Viewer
• Equivalent symbol switching according DeMorgan's Laws.
• Extract Logic Cone
• Trace buffers
• Find circuit between two gates/ports
• Add comments on Schematic
• Key board usage
• Manually Route

• Enable ECO mode

3. GofECO:  Graphical ECO Environment. Change the Partial Schematic by add/replace/modify circuits.

• GofECO Overview
• Insert Gate
• Change Gate
• Add Gate
• Delete Item
• Increase/Decrease Driver
• Connect gates ( Add wire, connection)
• Undo ECOs
• Save ECOs

4. GofCall: Netlist Processing APIs.

• GofCall Overview
• Run in Graphical mode
• Run in Text mode
• Run script in batch mode
• APIs list
• Use cases

5. Interactions:

• GofViewer can launch GofTrace, and if ECO mode is enabled in GofTrace, GofECO will be loaded.
• Drag&Drop is supported between GofViewer and GofTrace.
• Use Send marked lines to schematic feature to load gates from GofViewer to GofTrace.
• Use Copy cells to other schematic feature to transfer gates between GofTrace schematic windows
• Click mouse right button to pop up menu to do more interactive commands.

6. Usage:

• Check Usage for detail.
• gof -synlib lib0.lib -v lib1.vlib +libext+.v -y library_directory netlist0.v netlist1.v
