In one embodiment, at least some coupling components (e.g., metal layer wires, traces, lines, etc.) have a relatively dominant impact on delays and the delay is in part a function of both capacitance and resistance of the coupling component. In one embodiment, a system comprises a plurality of dominant characteristic oscillating rings, wherein each respective one of the plurality of dominant characteristic oscillating rings includes a respective dominant characteristic. Additional analysis can be performed correlating the dominant characteristic delay impact results with device fabrication and operation.

    摘要: Systems and methods for transition delay measuring are presented. A transition delay measuring method can include oscillating a signal between states and tracking an indication associated with an isolated attribute of the transitions between the states. Oscillations can include asymmetric transitions between the states and the tracked isolated attribute can be a delay in completing transitions between the states in one direction or vice versa. The asymmetric transitions can include transitions between the first state and the second state that are faster than slower transitions between the second state and the first state or vice versa. The tracked indication can be utilized in analysis of the isolated transition delay characteristics. The results can be utilized in analysis of various further features and characteristics (e.g., examination of leakage current related power consumption, timing of asymmetric operation, etc.). The analysis can include examination of fabrication process and operating parameters.

Responsive to detecting a logical transition of an input signal, one of the activation circuits is configured to activate a corresponding output circuit, which is configured to drive an output signal on an output node. A corresponding echo circuit is configured to be activated and to drive an input node responsive to activation of the corresponding output circuit. A corresponding one of the deactivation circuits is configured to deactivate the corresponding output circuit after a delay time has elapsed, whereas the corresponding echo circuit is deactivated in response thereto. A keeper circuit is configured to continue providing the output signal on the output node after deactivation of the corresponding output circuit.
