The primary goal of cellular radio systems — providing communication services to a large number of wireless data, video and mobile users — has become increasingly challenging in light of the rapidly evolving demand for these services and the resulting call for higher bandwidths and data rates in backhaul telecommunications systems, all at lower costs.

This growth has occurred in conjunction with increased tablet adoption in these markets. The widespread tablet adoption was driven by improved connectivity infrastructure has facilitated use of these devices as alternate content-viewing devices.

Figure 2 shows how this can be managed for an island that’s powered down. Because the internal core logic of the powered-down block is assumed to be effectively isolated from the rest of the chip, only the peripheral registers matter; their values are then corrupted (represented by C” in the figure). For a given application, the designer may have a more precise sense of what the powered-down values will be, so he or she should have some control over how the corruption is implemented.

Carrier aggregation of contiguous and non-contiguous spectrum bands has been identified as one of the most crucial aspects in the evolution towards LTE-Advanced, and has also been recognized as presenting a major challenge to the design of user equipment and eNodeBs. Cellular infrastructure vendors need a reliable test mobile to test their networks ahead of the availability of real terminals and handsets, and providing them with carrier aggregation capability at this early stage is proving essential to the development of the eNodeBs that will be used to roll out LTE-Advanced.

Selective flattening or preserving blocks based on timing criticality or other IP related issues allows more flexibility to the designer. At this point, the design can proceed through the rest of the flow following the traditional flat approach. Most of the heavy lifting in the design flow is during the pre-CTS step, which is done in a hierarchical style. But to retain the full benefit of top-level design timing/area/power closure from the flat approach, the design is finalized in a flat design style. Figure 3 shows a design view of a pseudo-flat flow.
