Clock skew (sometimes called timing skew) is a phenomenon in synchronous digital circuit systems (such as computer systems) in which the same sourced clock signal arrives at different components at different times due to gate or, in more advanced semiconductor technology, wire signal propagation delay. The instantaneous difference between the readings of any two clocks is called their skew. WebJun 27, 2010 · 8,771. what do you mean inter clock skew balancing. two methodologies: 1-all clocks are synchronous, so only one source, then skew blance during the CTS phase. 2- clocks are considered as asynchronous, in functional and in scan mode, then RTL code contains logic to avoid meta stability between two clock domains, and the CTS phase …

WebSep 1, 2024 · The Random algorithm can provide strong load balancing, but it does so by incurring high input replication. The FGSD algorithm can obtain good load balancing with greater skew.
