HFSS15: Large Scale DSO for Parametric Analysis

Large Scale DSO for parametric analysis operates through a non-graphical batch application called desktopjob. You can run the desktopjob command-line to perform parametric analysis DSO. The command-line interface supported by this batch program is consistent with the command-line used for regular DSO jobs.

Large Scale DSO is used for 'large scale parallel' jobs, which either fail or scale poorly as Regular DSO jobs. A Large Scale DSO job does not support the output of full parametric results, but produces 'reduced' datasets corresponding to predefined Rectangular plots. The extracted columns of data are saved as .csv files. Typically, there is one .csv file per-trace, per-variation. These .csv outputs can be used directly in downstream applications (for example, Excel, or custom programs that parse .csv files). They can also be Imported as Dataset Solutions for post processing. Non-Rectangular plots of the design (such as statistical eye or digital plot) are not extracted). In order to produce a new output you must re-run the analysis.

The basic process involves:

1. Prepare the model for Large Scale DSO Analysis

2. Submit the Large Scale DSO Job

3. Monitor the job’s progress

4. Post process the results
