Abstract

Embodiments of an integrated circuit that includes a debug circuit are described. This debug circuit is configured to test an asynchronous circuit by performing analog measurements on asynchronous signals associated with the asynchronous circuit, and includes a triggering module configured to gate the debug circuit based on one or more of the asynchronous signals. This triggering module has a continuous mode of operation and a single-shot mode of operation. A timing module within the debug circuit has a timing range exceeding a pre-determined value, and is configured to provide signals corresponding to a first time base or signals corresponding to a second time base. Furthermore, control logic within the debug circuit is configured to select a mode of operation and a given time base for the debug circuit, which is either the first time base or the second time base.
