The Vivado IDE displays the resources contained in a selected device in the Device window. Graphical sites display and are available for all of the device-specific resources, including all clock resources, such as BUFG, BUFGCTRL, BUFR, and BUFHCE components. The interior of the device is broken up into smaller rectangles called tiles, which are placement sites for the different types of logic primitives for the architecture.
The level of detail for displaying the device resources depends on the zoom level within the Device window. Some resources, such as specific slice resources, are not visible until you zoom into the device logic. Other resources, such as clock regions and I/O banks, appear even when viewing the whole device. In addition, you can control the display of specific objects or resources in the Device window, as described in Specifying Device Window Settings.
The Vivado IDE Device window displays resources as follows:
- I/O pads and clock objects
- Rectangles around the periphery and down the center of the device.
- I/O banks
- Thin, color-shaded rectangles just outside the row of I/O pads.
- Available I/O bank sites
- Color-filled I/O bank rectangles.
- Unbonded I/O banks
- Rectangles with a white X.
- I/O clock pads
- Filled-in rectangles.
