This paper describes the comparison of input stimuli as a means of testing mixed-signal
circuits. Current testing that measures the integral of the power supply current in the time-
domain is used to detect faults. The main objective is to achieve real-time testing in which
there is no need to analyze the results of testing. Simulation results show that a step-voltage
input stimulus is effective for detection of bridging and breaking faults in an A/D converter.
Since this input signal allows the current to be measured at discrete time intervals, it is …

The lack of a general methodology and notation has been identified as one of the main
obstacles bedeviling system-on-chip designers. Nevertheless, there is a lot of confusion
about what SLD (System Level Design) means and which SLDL (System Level Design
Language) is the most appropriate. With SOC demands there has been recently high
interest in system level design, particularly, HW/SW codesign. In order to accommodate SW,
the system companies as well as EDA vendors would like to use C as the language for …
