GDS viewer
The GDS viewer shows the finished physical layout of your chip — the actual geometry that would be sent to a foundry. It's where your design stops being code and becomes silicon.
What the GDS shows#
GDS is the standard layout format produced at the end of a successful run. Opening it in the viewer, you see every standard cell placed on the die and the metal wiring that connects them — the concrete result of placement and routing.

Navigating the layout#
- Pan and zoom to move from the whole die down to individual cells.
- Spot dense regions — heavy congestion is often where routing or signoff struggled.
- Relate what you see here back to the numbers in analysis, like area and utilisation.
Layers#
Reading the colours
A layout is built from stacked layers — the base cells plus several metal routing layers, each drawn in its own colour. Higher metal layers carry longer connections across the die. To see the logic those wires implement, switch to the schematic viewer.
