摘要:
A method of testing a programmable device begins by programming at least a portion of the programmable device in accordance with at least a portion of an application to produce a programmed circuit, wherein the programmed circuit includes an input sequential element and an output sequential element. The method continues by providing a test input to the programmed circuit. The method continues by triggering the input sequential element to temporarily store the test input based on a first edge of the test clock. The method continues by triggering the output sequential element to temporarily store a test output of the programmed circuit based on a second edge of the test clock. The method continues by capturing the test output of the programmed circuit in accordance with the second edge of the test clock.
