When this option is turned on, the next time you compile, the Quartus II software
automatically runs the add constraints script. Turn off this option if you do not want
the script to run automatically.
When this option is turned on, IP Toolbench parses and updates the example design
file. It only updates sections that are between the following markers:
<<START MEGAWIZARD INSERT <tagname>
<<END MEGAWIZARD INSERT <tagname>
If you edit the example design file, ensure that your changes are outside of the
markers or remove the markers. Once you remove the markers, you must keep the
file updated, because IP Toolbench can no longer update the file.
When this option is turned on, IP Toolbench automatically overwrites the PLL.Turn off
this option, if you do not want the wizard to overwrite the PLL. The first time you
create a custom variation, you must turn on Update example design system PLL.
The constraints script analyzes your design, to automatically extract the hierarchy to
your variation. To prevent the constraints script analyzing your design, turn on
Enable hierarchy control, and enter the correct hierarchy path to your controller.
The hierarchy path is the path to your QDRII SRAM controller, minus the top-level
name. The hierarchy entered in the wizard must match your design, because the
constraints scripts rely on this path for correct operation.
This string prefixes the pin names for the FPGA pins that are connected to the QDRII
SRAM controller.
