You can create a new core in SmartGen only after you have created a workspace.
To create a new core in SmartGen:
Select a core type in the Categories tab (Arithmetic, Comparator, Converters, etc.). The Variety View window displays the list of configurable cores.
Double-click the core
variety you wish to generate, or right-click and choose Create
Core. The core configuration dialog box appears.
The configuration dialog box varies depending on which core you select.
Set the parameters for your core and click Generate. The Save As dialog box appears.
Specify the name of your
new core and click Save to continue.
SmartGen saves your core to the specified directory and adds your core
to your workspace (in the Configured Core View Window). If you deliberately
save the core in a different directory than the workspace, the core will
be saved, but will not be added to the workspace.
Your core remains in the workspace until you choose to Remove
it.
Note: You cannot create two cores with the same name. SmartGen is case-insensitive; "core_A" is equivalent to "core_a".
