Statistical Experimental Design and Analysis
Example of Analysis Results
Example of Analysis Results
The results of an experiment are available in the .dex file.
This output file contains:
• Ordered Data Table—for each simulated response.
• DEX Mean Table—which provides the ranked list of factors (not including the
interactions). The ranking is from the most important factor to least important factor.
• Formal Test of Significance—based on the Lenth’s method.
• Multi-Responses—a summary of the screening experiments for each response in the
case of multi-responses.
• Unordered Data Table (CSV Table)—giving the simulation results.
The results of an example analysis are presented below. The example used is cmos_ring.cir
(available in the directory: $MGC_AMS_HOME/examples/dex/). Two response functions are
defined which are the oscillation frequency 30 MHz < OSCFREQ < 50 MHz, and the AC
switching power dissipation: ACPOWER < 5 MW.
This analysis is performed with respect to 34 noise factors. Note that the .dex file gives the
name and the properties of each factor. A dummy name is associated to each factor to get more
compact tables. The control factors are designated by C1, C2, C3, ... and the noise factors by
N1, N2, N3, and so on.
