13.3 PlanAhead - Importing partition results in "ERROR:NGDBuild:1218" and "ERROR:NGDBuild:1037" due to XST Import on Windows

Description

If I import a partition using the PlanAhead software, NGDBuild issues the following errors:

"ERROR:NgdBuild:1218 - 'RAMB36E1' dedicated resource pin ' ' on instance ' ' is used in this implementation, but is not used in the previous implementation."

"When this dedicated resource is connected across a Partition boundary, changes to the driver will cause this difference in the imported Partition. Ensure the drivers are the same in each iteration, or re-implement and export Partition."

These errors are accompanied by the following error:

"ERROR:NgdBuild:1037 - The logic for imported Partition ' ' using previous implementation '.ngd' has been modified. This situation can occur when the source for the Partition was modified but the Partition was not re-implemented and exported. You must re-implement and export the Partition before it can be imported into this design."

Solution

This problem is specific to importing partitions in 13.3 XST on all Windows platforms. The issue is a corrupt attribute in the NGC file that only affects the PlanAhead software.

To work around this issue, use the command line flow.

A patch for PlanAhead 13.3 software is also available from the following link:

This issue is resolved in the PlanAhead 13.4 software.
