GofTrace Overview:

• GofTrace is a fully interactive Netlist to Schematic Engine.
• Other EDA tools draw much more than enough logic when tracing fanout/fanin. Even worse they draw the fixed placement format schematic, you can't adjust gates position on the schematic. After several iteration, you most likely get confused.
• GofTrace gives more flexibility in drawing schematic. You can draw only the portion of logic that you have interest in.
• Use Mouse-Middle-Button (Press both buttons if the mouse has only two buttons) to click on the pin you want to trace. 
• If the pin is input port, the driver gate will appear with a line connecting to the pin, move the gate while moving the mouse, release the Mouse-Middle-Button to place the gate.
• If the pin is output port, all fanout gates will appear with their pins connecting to the port by lines. Move the gates while moving the mouse, release the mouse middle button to place the gates.
• The gates can be placed anywhere you like. After a schematic is drawn, you can adjust placement of the gates.
• Any redundant gates or nets can be deleted by pressing Delete key on keyboard.
• The 'Place & Route' feature makes creating schematic much easier. And 'extract logic cone' draws the whole logic cone you like at one click.
• Natural symbol suport. ("-synlib technology_library" is preferred to be used in the command line for symbol display)

• Move the gates around after the schematic is drawn.

• Choose manually place & route or automatically place & route.

• GOF automatically places & routes the gates on the schematic.

• You can manually route the wires as you like.

• Click zoom in , zoom out buttons to zoom in/out schematic  

• Do Extract Logic Cone to speed up bringing up related gates.

• The whole logic cone driving the selected gate is drawn.

• Check ECO checkbutton to enable GofECO, ECO mode. In ECO mode, trace function is still valid. Anything deleted will be saved as ECO actions.
