GOF integrates three function units, GofViewer, GofTrace, GofECO

1. GofViewer: Text Mode Netlist Browser. It has search, fanin/out, modify and save netlist features.

1. GofViewer Overview.
2. Read in design and Reload design
3. Save session and Load session
4. Open Netlist
5. Driver and Load of Net
6. Edit Module
7. Save module
8. Calculate area
9. Goto Line number
10. Launch GofTrace
11. Actions Menu
12. Search Function
13. Setup
14. Change Fonts size short cut
15. Create Waveform Restore File
16. Design Statistic
17. RTL Viewer
18. Perl Script Interface
• GOF Perl APIs
• GOF Perl example
19. Diff utility
20. Matching nets from RTL to Netlist
21. List Fanin Fanout Endpoints
22. Send marked lines to schematic
23. Hyperlink for information fast access

2. GofTrace: Partial Schematic Creation from netlist. It draws only gates and connections that users have interest in.

1. GofTrace Overview.
2. Trace fanin fanout
3. Partial Schematic
4. Save and Open Schematic
5. List gate and load gate
6. View options
7. Clock tree
8. Waveform Restore File
9. Zoom in Zoom out
10. Search cells and nets
11. Copy cells to
12. Edit cell
13. Cell description
14. SDF timing
15. Cell position
16. Enable ECO mode
17. Place & Route
    • Auto Place & Route
    • Auto Place
    • Auto Route
    • Reset Route
18. View cells in layout
19. Equivalent symbol switching according DeMorgan's Laws.
20. Extract Logic Cone
21. Trace buffers
22. Find circuit between two gates/ports
23. Add comments on the Schematic
24. Key board usage
25. Manually Route

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

1. GofECO Overview.
2. Add cells.
3. Insert cells.
4. Replace cells.
5. Modify cells.
6. Connect cells. ( Add wire, connection)
7. Delete items.
8. Add Macro Cell.
9. Metal only ECO.
10. Undo ECOs.
11. Save ECOs.
12. Logic Cone ECO.

4. Interactions:

• GofViewer can launch GofTrace, and if ECO mode is enabled in GofTrace, GofECO will be loaded.
• Drag&Drop is supported from GofViewer to 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

5. Usage:

• gof -synlib lib0.lib -synlib lib1.lib +libext+.v -y library_directory netlist0.v netlist1.v     
• A splash window appears which display the tools version and loading status. A progressing bar tells how much the file has been uploaded.
• 
• When all files are loaded, GofViewer window pops up.
• Check Usage for detail.
