WebMar 29, 2024 · To include the propagated clock latency (due to CTS) in the IO port delays, you should also use the -reference_pin option with the set_input_delay and set_output_delay commands. This ties the network latency used for the IO to the propagated latency of some flop's clock pin in the core. WebAug 21, 2024 · The ICG cell allows to stop the clock signal propagation beyond it and it helps to reduce dynamic power consumption in the design. The architecture of ICG Cell: There are various ways to implement the clock gating techniques and there are many architectures of ICG cells also. Here the most common architecture is Latch-AND based …

WebThe purpose of building a clock tree is enable the clock input to reach every element and to ensure a zero clock skew. H-tree is a common methodology followed in CTS. Before attempting a CTS run in TritonCTS tool, if the slack was attempted to be reduced in previous run, the netlist may have gotten modified by cell replacement techniques. WebClock uncertainty is the time difference between the arrivals of clock signals at registers in one clock domain or between domains. Pre-layout and Post-layout Uncertainty Pre CTS uncertainty is clock skew, clock Jitter and margin. After CTS skew is calculated from the actual propagated value of the clock. We can have some margin of skew + Jitter.
WebDec 24, 2015 · Figure 1 A clock gating check. ... Because it is an and cell, a high on gating signal UAND0/A opens up gating cell and allows clock to propagate through. Clock gating check is intended to validate that gating pin transition does not create an active edge for fanout clock. For positive edge-triggered logic, this implies that rising edge of ...

WebFor propagated clocks, NanoTime calculates the cumulative delays along the clock network, including wire delay. The opposite is an ideal clock. For ideal clocks, NanoTime uses the latency values set on clocks, ports, or pins using the set_clock_latency command, or zero latency if none has been set.
