This topic provides a high-level overview of the new features in the IC23.1 base release and subsequent ISR releases.
IC23.1 ISR3
Syncing Design Intent When Only Schematic is Open
It is now possible to sync a design intent in a schematic view with no corresponding layout view opened. You can do this by selecting the library, cell, and view name from the Sync Design Intents from Layout form. The Sync Design Intents from Layout form is displayed when you right-click and choose Design Intent – Sync... – Sync All Design Intent, or click on the Sync button on the toolbar.
New Design Intent columns in the Navigator Assistant
The following two columns are now available in the Naigator assistant to show the design intent information. These columns are only displayed when you are in a design intent category.
- DI Status column displays the implementation status of each design intent.
- DI Profile column displays the profile of each design intent.
IC23.1 ISR2
Design Intent Enhancements
The Virtuoso Design Intent has been enhanced with the following improvements:
- Use the Select All Members option in the shortcut menu when placing the mouse cursor over a design intent in the Navigator assistant.
- A tooltip is displayed when you place the mouse cursor on a design intent in Constraint Manager.
- Double-clicking a design intent glyph is an easy and quick way to open the Edit Design Intent form.
- A new Elliptical style to identify the device/pin design intent annotation has been introduced. See Create Design Intent Form.
- Use the Check and Save button on the Design Intent toolbar to preview an alert for the synchronization required on design intents. You can now view the alert without having the need of opening the schematic and layout views together.
IC23.1 ISR1
New Design Intent SKILL Function
The ciDIUpdateArrowDirections SKILL function lets you update high current design intent arrows that do not follow the conventional current flow direction.
IC23.1 Base
Creating a Critical Net Design Intent
You can now create Critical Net design intents for identifying nets that you consider to be critical in the design. You can filter for critical net design intents using the Analyze Connectivity form in the Virtuoso Layout Editor.
Hierarchy Propagation
You can now run auto propagation across multiple hierarchies for selected nets or HighCurrent design intents. The feature lets you push nets and HighCurrent design intents up or down the hierarchy, and it also provides a consistency check to report discrepancies.
