PlanAhead - How to swap placement locations?


After an implementation run, I want to swap the location of two BRAMs.

How can I do that?


In PlanAhead 12.x tool, this can be done bymanually modifying each component's property.

  1. Select the concernedinstance fromany views (e.g. netlist view), and view its property view
  2. In the property view, select the Attributes tab
  3. Manually edit the LOC string to the desired XmYn location
  4. Click Apply to save the change

The above actions will fix unfixed placements.

In PlanAhead 13.1 software and later, there is a simpler way to swap placement locations.

  1. Select two component instances from any of the available views. Hold the Ctrl key while clicking to select multiple ports.
  2. Right-click and select Swap Locations.

If you swap two components which are not yet fixed, the act of swapping them also causes them to be fixed.
