WebNov 14, 2005 · Types of clock trees. There are many clock tree structures used widely in the design industry, each of which has its own merits and demerits. We will discuss four structures in this article: H-tree (figure 1), balance tree (figure 2), the spine tree (figure 3) and distributed driven buffer tree (figure 4). WebCTS is the process of connecting the clocks to all clock pin of sequential circuits by using inverters/buffers in order to balance the skew and to minimize the insertion …
WebNov 20, 2015 · To enable boundary cell insertion during clock tree synthesis, 1. Specify the buffers (or inverters) used for boundary cell insertion. 2. Enable boundary cell insertion by using the set_clock_tree_options -insert_boundary_cell true command. If you enable boundary cell insertion, it applies to all clock trees. Webcan be enabled by setting this app_option to true before running clock_opt • Ensure that all post-CTS settings are applied before clock_opt so that timing seen by CCD is accurate CCD in build_clock • Performs timing driven clock tree building and optimization based on the balance points/offsets derived by the tool (setup and hold) • Finally clock nets are …
