GVT gives users full control of how the schematic is drawn, so that users can focus on the logic under investigation and users are not distracted by unrelated redundant information.
The following dynamic schematic shows how user can control the expansion of a schematic by mouse clicks.

For the small size ECOs, it is is not practical to resynthesize multi-million gates design to have only one inverter added. It's not a good practice either to use text editor to change million instances netlist. Normally, 85% of functional ECOs involve less than 20 gates. For those 85% small size or replicated ECOs, global mode Automatic ECO is over-killed and inefficient. GOF/GVT gives users flexibilities to choose GUI and Script mode for those small size or replicated ECOs.
The following dynamic schematic shows how user can do ECO by mouse clicks.

GVT has many built-in features to speed up netlist debug process. For example, 'Driver Until Non Buffer' feature can draw the whole clock tree driver path at one mouse click.
The following dynamic schematic shows how to trace clock buffer by one click.
