Discuss the relationship and impacts of CSA, USA PATRIOT ACT, and FISA. Also discuss the current status of these laws and the replacement of these laws.

Sample Solution

near the buffers or on the path of the clock source. Hence path sharing of the sinks while tracing back to the clock source is very less. The buffers are placed in every launch nodes, branching from the main path as the tree goes lower towards the sink. Hence the clock tree has great depth for buffer placement. The buffer placement depth increases the path sharing between the clock sources and the sinks reduces. With the increase in the path sharing of the sinks to the source there is reduction in the on chip variations on the distribution as there is no effect of skew between different sinks on the same path due to process variations. Clock tree is adversely affected by this as the number of sinks having a common path to the source is very low. Clock Mesh- The structure of the clock mesh is in the form of a grid which maybe organized in either a uniform or a non-uniform fashion. A window which is formed from the interconnecting grid contains clock sinks which may be grouped based on various factors such as capacitance, resistance or both. The non-uniformity is due to the uneven grouping of the sinks in the window based on a constraint. The buffers are placed at the nodes of the clock mesh, which are distributed based on the density of the sinks in the window. As it forms a grid structure the path sharing of the sinks to the source is more as a node is connected to every other node. Thus the buffer depth is very shallow, maybe a single stage. Hence there is very less induction of skew due to the process variations. The clock tree consumes less power when compared to the cock mesh as there is increase in the wire length and hence total wire capacitance of the mesh which amounts for higher power consumption. But as the technology node reduces and the logic becomes denser, the skew due to the process variations becomes more predominant in clock tree rather than in clock
