GVT Netlist Debug Tool
- Incremental schematic
- Fully interactive netlist to schematic converter
- Click-Mouse to direct the schematic generation
- Fast key to trace clock tree
- GUI ECO is done one the fly
- What you see is what you will get
Fully Interactive Schematic
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.

GUI Mode ECO
Sometimes, it doesn't make sense 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 a Giga-byte size netlist. If a design is reasonably verified, those ECOs involving more than 20 gates should be less than 10%. For those 90% small size or replicated ECOs, global mode Automatic ECO is over-killed and inefficient. 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.

Netlist Debug Speed Up
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.
