The powerful Partial Schematic feature can isolate a logic cone by several mouse clicking. The following example shows how to create a circuit from one starting cell. GofViewer window lists netlist and hierarchy, use search function to find the cell "INVX3 U890'. Launch GofTrace, the "INVX3 U890" is on the schematic. Using mouse middle button to click U890 input pin and output pin, a circuit will be created.

• You can move cells anywhere or back trace driver or forward trace load by clicking any pin.
• Assume n1443 should drive U932/B, you can enable GofECO by check ECO checkbutton in GofTrace.

• Delete the line connecting U890 to U932.  By clicking
• Add an BUFX2 cell.  Using button
• Press middle button on U932/B move to ECO cell's output release. Connection created.
• Press middle button on ECO cell's input and move to U1060's output and release. Connection created.
• Save ECO. By clicking button
