Dynamic Timing Analysis

	Dynamic Timing Analysis Dynamic timing analysis is a verification of circuit timing by applying test vectors to the circuit. It is a form of simulation that tests circuit timing in its functional context.

	Test Vector In computer science and engineering, a test vector is a set of inputs provided to a system in order to test that system. In software development, test vectors are a methodology of software testing and software verification and validation. Rationale In computer science and engineering, a system acts as a computable function. An example of a specific function could be y = f(x) where y is the output of the system and x is the input; however, most systems' inputs are not one-dimensional. When the inputs are multi-dimensional, we could say that the system takes the form y = f(x_1, x_2, ...) ; however, we can generalize this equation to a general form Y = C(X) where Y is the result of the system's execution, C belongs to the set of computable functions, and X is an input vector. While testing the system, various test vectors must be used to examine the system's behavior with differing inputs. Example For example, consider a login page with two input fields: a username field and a pas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Dynamic Timing Verification Dynamic timing verification is a verification that an ASIC design is fast enough to run without errors at the targeted clock rate. This is accomplished by simulating the design files used to synthesize the integrated circuit (IC) design. This is in contrast to static timing analysis, which has a similar goal as dynamic timing verification except it does not require simulating the real functionality of the IC."ASIC world: vol 10", page 13, October 2003 Hobbyists often perform a type of dynamic timing verification when they over-clock the CPUs in their computers in order to find the fastest clock rate at which they can run the CPU without errors. This is a type of dynamic timing verification that is performed after the silicon is manufactured. In the field of ASIC design, this timing verification is preferably performed before manufacturing the IC in order to make sure that IC works under the required conditions before mass production of the IC.

	Static Timing Analysis Static timing analysis (STA) is a simulation method of computing the expected timing of a synchronous digital circuit without requiring a simulation of the full circuit. High-performance integrated circuits have traditionally been characterized by the clock frequency at which they operate. Measuring the ability of a circuit to operate at the specified speed requires an ability to measure, during the design process, its delay at numerous steps. Moreover, delay calculation must be incorporated into the inner loop of timing optimizers at various phases of design, such as logic synthesis, layout ( placement and routing), and in in-place optimizations performed late in the design cycle. While such timing measurements can theoretically be performed using a rigorous circuit simulation, such an approach is liable to be too slow to be practical. Static timing analysis plays a vital role in facilitating the fast and reasonably accurate measurement of circuit timing. The speedup come ...
