System and method for examining asymetric operations

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.

1. A delay measuring system comprising:
a first transition stage including a first component under test, the first transition stage operable to cause a first inversion transition in a signal; a second transition stage including a second component under test, the second transition stage operable to cause a second inversion transition in the signal, wherein an amount of time to complete the first inversion transition is different from an amount of time to complete the second inversion transition; and a transition completion detection component coupled to the first component under test and the second component under test, wherein the transition completion detection component is operable to detect an indication of a delay measurement between initiating the second inversion transition to completing the second inversion transition.
