Changing I/O Pin Attributes

The I/O Pins tab lets you update the layer, width, height, number, criticality, and signal type of existing pins. This table is initialized with Term and Net Names from the symbol view of the selected soft block.

When you click the I/O Pins tab, the form changes to display the I/O Pins table as shown below.

You can select one or more rows to modify in the table. If you select multiple rows, the fields below the table list the respective values only if they are same for the selected rows. Otherwise, the fields display AS IS.

   The Edit Soft Blocks form is displayed.
2. Select the blocks whose pins you want to change.
3. Select the entry in the table that you want to update.

5. Do one of the following.
   • Click Update to update the selected entries in the table.
   • Click Update All to update all the entries in the table.
