AR# 45473: PlanAhead - How can I open the partially routed design in PlanAhead?
PlanAhead - How can I open the partially routed design in PlanAhead?
How can I open a partially routed ISE design in PlanAhead?
This can become necessary in two situations:
PAR is canceled, fails or completes with zero Errors, but the flow stops in PlanAhead due to the design failing to route with a warning, WARNING:PAR:100. "PAR ERROR" is returned on Design Runs. Because implementation does not complete, I cannot open the Implemented Design to debug the partial placement.
I have a partial or fully routed .ncd file created outside of PlanAhead. Is there a way to open this .ncd file in PlanAhead for analysis?
For situation 1, a user can "Import Placement" for viewing and analysis using the following steps:
Open the Netlist Design.
The Import Placement option in step 2 will not be available without an active netlist open.
Select File -> Import -> Import Placement.
Browse and select the desired .ncd file.
For an .ncd file generated outside of PlanAhead, create a new project and use the Import Place & Route results option in the New Project Wizard.
Select File -> New Project in the PlanAhead GUI.
Click Next on the first page of the New Project Wizard.
Choose a project name and location and click Next.
Select Import ISE Place & Route results.
Continue through the wizard to create the project.
The partially routed .ncd file will be imported and can be opened and analyzed as desired.
