Soft Block Editing
The Edit Soft Blocks command lets you modify the soft blocks in your design. Use this command if you need to modify the attributes of individual soft blocks to take account of placement and connectivity requirements in your design.
This command is recommended if you want to make changes that do not require the physical hierarchy to be regenerated. If you need to make more radical changes (by, for example, generating new soft blocks or flattening others that you no longer require), use the Launch – Configure Physical Hierarchy command in Soft Block mode.
Using the Edit Soft Blocks command, you can modify
- The type of soft block that will be created.
- The height, width, area, or shape of the place and route boundary.
- The length, width, layer, and signal type of soft pins.
- Routing and placement obstructions inside the block.
A number of Virtuoso Layout Suite commands have been enhanced to support Level-1 Editing mode, which is the ability to edit objects inside a soft block without using the Descend or Edit In Place commands. This section further describes how to enable Level-1 Editing mode and how to use the enhanced Move, Stretch, Reshape, and Chop commands.
