During interactive routing, you use SDR for two modes of routing checks, one based on the current density and the other on the maximum resistance. The following are the tasks for interactive SDR checks to avoid EM and maximum resistance violations in the design while performing simulation-driven interactive routing:
- Visualize the Current Distribution
Identifies the net connections that either consume or generate the most current.
- Run the Current Density Check
Estimates the current in the edited wire and lets you create a design with the appropriate width of wire based on the estimated EM value.
- Run the Maximum Resistance Check
Connects the pins interactively and automatically estimates the final resistance between the two pins.
- Connect Twigs
Connects multiple pins automatically with the appropriate wires and vias.
- Taper Wires
Adjusts the width of each segment independently.
