While design for manufacturing (DFM) flows have been implemented in the industry, DFM flows at advanced CMOS nodes face several challenges that threaten widespread adoption. 

In this article by Mark Mason from Electronic Design, the question of DFM Software’s future is broached.

Most modern spectrum analyzers have at least one method for making a time-gated measurement of the signal spectrum. The purpose of time-gated spectrum analysis is to measure the spectrum of a periodic signal during a specific portion of time. An example is to observe the spectrum of a pulsed signal only during the time that the pulse is on—not during the transitional or off periods of the burst. (In many cases, the spectral components that contribute to the pulse’s rising and falling edge will mask spectral components that contribute to the pulse’s on time.) Gating is also useful for measuring channel power, adjacent channel power, and spectral emission mask measurements of a modulated signal that is bursted in the time domain.

Time gating on these signals can often be challenging. Issues like narrow pulse widths, wide bandwidth signals, and lack of convenient gate triggers can make time gating difficult. This article examines a signal that is pulsed in the time domain. It then performs a time-gated measurement on that signal. As a result, it is possible to investigate the different types of time gating that are available and what applications are most appropriate for which methods. Gate triggering will also be examined, as well as measuring wide-bandwidth signals.
