General Description: When you edit a placed Block RAM component for a Virtex design, it should be possible to apply initial values to the Block RAM by clicking on the "Show/Hide Attributes" button and editing the various fields. Applying these changes to the initial values should be as simple as clicking on the "Saves Changes and Closes Window" button.
However, this is not the case. After you have saved changes and closed, FPGA Editor generates the following warning:
WARNING:FPGAEditor:41 - The "Init00" attribute item is not used by BLOCK RAM type components.
Furthermore, selecting the Block RAM and clicking on the ATTRIB button followed by the CONFIGURATION tab reveals that no changes to the initial values have been saved by FPGA Editor.
