Sources and Sinks Map

Specifies whether or not the source and sink map should be displayed.

Environment Variable: weSdrSourceSinkMap

Display Sources and Sinks Map Clusters

Shows the current distribution across pin clusters as a thermal map.

Display Sources and Sinks Map Pins

Shows the current distribution on a single pin as a thermal map.

Hide Sources and Sinks Map

Hides the thermal map showing current distribution across pins and clusters. This is the default option.

EM Width Multiplier

Helps in increasing or reducing the wires width compared to the estimated width required to satisfy the EM value

Environment Variable: weSdrWidthMultiplier

Checker Mode

Lets you choose the SDR checker mode to be used for current and resistance estimation.

Environment Variable: weSdrCheckMode

Enforce

Estimates the current or resistance in the edited wire and vias according to the EAD settings (dataset, temperature, and current scaling) and automatically calculates the wire width and via cuts to avoid EM or maxResistance violations.

Notify

Estimates the current in the edited wire using a color code based on EAD EM violations color settings. The color is computed to represent the EM or maxResistance violation that is reported by the EAD checker after routing.

Off

Retains the existing wire width and there is no feedback on estimated current or resistance.

Current Estimation Mode

Lets you control how the current in the edited wire and via is estimated and calculated.

Environment Variable: weSdrCurrentEstimationMode

Auto

Estimates the current automatically in the last section of the wire according to the connected objects and flightline targets.

Sum Connected Pins Current

Sums up the current of all the physically connected pins.

Maintain Constant Current

Inherits the current from the previous wires.

Nearest Island Current

Uses the current of all the pins connected by the nearest flightline.

Automatically Connect Twigs

Toggles the twig modes between ON and OFF.

Environment Variable: weAutoTwigMode

Allow Twig Connection

Sets the allowed direction of twigs to either the vertical direction, the horizontal direction, or both. This toolbar button is enabled only when the Automatically Connect Twigs option is set to on.

Environment Variable: weAutoTwigDirection

Allow vertical and horizontal twigs

Allows twigs to be inserted in both vertical and horizontal direction.

Allow vertical twigs

Set the twigs in vertical direction.

Allow horizontal twigs

Set the twigs in horizontal direction.

Via Alignment

Controls the alignment and orientation of vias or via stacks created on each twig over the trunk. You can choose the via alignment depending upon the via direction mode that is selected.

The Via Alignment button on the SDR toolbar is enabled only when Automatically Connect Twigs is ON.

Environment Variable: weAutoTwigTrunkViaAlignment, weAutoTwigTrunkViaDirection

Via Alignment: Left Or Bottom (For Twig Via Direction)

Creates vias or via stacks in the direction of the twig that is vertical and bottom-aligned to the trunk.

Via Alignment: Center (For Twig Via Direction)

Creates vias or via stacks in the direction of the twig that is vertical and aligned to the trunk center. This is the default alignment mode.

Via Alignment: Right Or Top (For Twig Via Direction)

Creates vias or via stacks in the direction of the twig that is vertical and top-aligned to the trunk.

Via Alignment: Left Or Bottom (For Trunk Via Direction)

Creates vias or via stacks in the direction of the trunk that is horizontal and left-aligned to the twig.

Via Alignment: Center (For Trunk Via Direction)

Creates vias or via stacks in the direction of the trunk that is horizontal and aligned to the twig center. This is the default alignment mode.

Via Alignment: Right Or Top (For Trunk Via Direction)

Creates vias or via stacks in the direction of the trunk that is horizontal and right-aligned to the trunk.

DI as Dataset

Sets the EAD dataset called DI with the design intent information.

Environment Variable: weSdrDIDatasetName, weSdrDatasetNamingMethod

Import DI as Dataset

Imports or updates the EAD dataset called DI with the design intent information in the layout view.

Sync and import DI as Dataset

Syncs the DI high current information from the schematic to the layout and then converts it into a dataset.

Electrically Aware Pin Sizing

Displays the Electrically Aware Pin Sizing form and the Pin Tool – Pin Browser window. The Electrically Aware Pin Sizing form lets you identify pins that do not meet electrical requirements and automatically fix the reported violations.

Options

Displays the SDR Options form.

SDR Task Assistant

Displays the SDR documentation in task assistant.
