Simulation Report
Simulation report To generate a report, select the Report command from the Workspace menu or click on the Report icon of the toolbar, this activates the Report options window:
In this dialog window, the user can configure the contents of the generated report, by checking or un-checking following items:
- Scenario - to indicate whether all scenario parameters should be included
- Simulation control - to indicate whether simulation control parameters should be reflected
- Generated signals and ICE results - to indicate if the simulation results should be included
The user can also choose to expand or not all tabular data by checking or unchecking the Expand tabular data option.
Eventually, the user can choose the output format of the report:
- HTML File (default)
- Comma Separated Values (CSV) File
- XML File
- User specified format (then choosing a file containing stylesheet, see explanation below)
Click on Ok to validate the report options and start the generation of the report.
As far as simulation results are concerned, the signals are presented in the report by means of following information:
- mean
- variance
- samples of the cumulated distribution function (defined though a defined set of percentiles) if Expand tabular data option has been selected
For all other data types the output is similar to their display in the workspace tree view except that couples of values defining user-defined random data, functions, and radiation patterns are fully expanded.
All SEAMCAT reports are generated through a XSLT stylesheet, and it is posible for users to specify a custom stylesheet to use instead. It is also posible and recommended to produce the user-specific stylesheet by editing the SEAMCAT's built-in stylesheets, which can be found in the SEAMCAT home folder. XSLT is a standardized technology used in many applications for transforming an XML source document into a desired format. The XML report in SEAMCAT contains ALL information contained in workspace even those parameters not used in simulation. There are plenty of good books on XSLT and plenty of visual design tools available.
The World Wide Web Consortium http://www.w3c.org has several good, free and online courses on this subject. A copy of the official W3C recommendation, containing a good source of information,can be found at http://www.w3.org/TR/xslt.
