Hierarchical clock gating
Webnaming styles, unused pins, test inputs and clock gating. Critical files such as RTL, netlists and libraries are automatically located. All auto-setup information is listed in a summary report. Guided Setup Formality can account for synthesis optimizations using a guided setup file automatically generated by Design Compiler or Fusion Compiler. WebWhen the hierarchical clock-gating feature is enabled, and more than one clock domain contains a view to a register that is visible in the programmers model or an access point, …

Web25 de set. de 2009 · must tell the tool your target clock period. The following commands tell the tool that the pin named clkis the clock and that your desired clock period is 2 nanoseconds. You need to set the clock period constraint carefully. If the period is unrealistically small, then the tools will spend forever trying to meet timing and ultimately … Web7 de out. de 2015 · Abstract: A clock mesh, in which clock signals are shorted at mesh grid, is less susceptible to on-chip process variation, and so it has widely been studied …
WebSynchronizer Chain Statistics Report in the Timing Analyzer. 1.6.1. Tri-State Signals. 1.6.1. Tri-State Signals. Use tri-state signals only when they are attached to top-level bidirectional or output pins. Avoid lower-level bidirectional pins. Also avoid using the Z logic value unless it is driving an output or bidirectional pin. Web4 de dez. de 2009 · In our designs we normally implement a hierarchical clock-gating technique that puts multiple levels of clock-gating cells in the design. The multiple levels also exist because clocks from the various sources (PLL, external oscillator, dividers) get distributed throughout the chip via a clock-distribution network that generates gated and …
WebIn simplest form a clock gating can be achieved by using an AND gate as shown in picture below. Figure 1: AND gate-based clock gating. The clock enable signal, generated by a combinatorial logic, controls when to provide the clock to the downstream logic (FF in the above figure). When enable is 1, the clock will be provided to FF and when ... Web21 de dez. de 2016 · There are two scenarios to connect the test pins of the clock-gating logic: • Set up observability logic prior to mapping : If the control signal is specified before …
