Explode Length Tuning Object to Free Primitives
Applied Parameters: Action=Explode | Object=LengthTuning
Summary
This command is used to convert a chosen length tuning object to its constituent primitives. A length tuning 'accordion' is a 'smart union' - a group object that is comprised of primitive track and/or arc segments. As such, it can be selected, modified and deleted as a single object.
Accordion style length tuning, also known as serpentine routing, is a standard design technique for high-speed nets with critical timing requirements. It is used to ensure that critical nets have matched lengths, by adding accordion sections to shorter route paths. Accordions are added to an existing route using the
Interactive Length Tuning tool.
Access
This command can be accessed from the PCB Editor by:
- Choosing the Tools » Convert » Explode Length Tuning To Free Primitives command from the main menus.
- Right-clicking in the workspace (over an object or not) and choosing the Unions » Explode Length Tuning To Free Primitives command from the context menu.
Use
After launching the command, the cursor will change to a cross-hair and you will be prompted to select a length tuning object. Position the cursor over the required length tuning object to explode and click, or press Enter. The single, smart union object will be reverted back to its individual track and/or arc primitives.
Continue to explode further length tuning objects, or right-click, or press Esc, to exit.
Tips
- If an accordion object is already selected when the command is launched, it will be converted, but you will not remain in conversion mode.
- Although there is no actual command to regroup an exploded length tuning object, you can use the Undo command to achieve this.
