CST PCB STUDIO File Block

Block Selection Tree: Field SimulatorsCST PCB STUDIO file block

 

This type of block implements the import of a CST PCB STUDIO™ file. A CST PCB STUDIO file block always refers to a file on disk (or any other storage medium of course).

 

The block is characterized by the properties listed below. To modify the values use the Block Properties – Parameters dialog box.

 

Export Currents for EMI

An equivalent current source of this block is generated for AC tasks if this parameter is checked and the PCB model was generated for EMI analysis. See the AC Simulation Task page for details.

Export Fields for EMI

An equivalent field source of this block is generated for AC tasks if this parameter is checked and the PCB model was generated for EMI analysis. See the AC Simulation Task page for details.

General Usage

This type of block is not parameterized. The number of internal ports is automatically set according to the terminals defined for the PEEC or TL model created from the CST PCB STUDIO™ file. If the created model is not up to date it will be updated automatically by CST PCB STUDIO™. A CST PCB STUDIO™ file without a created PEEC or TL model can not be used by this block, because in this case the only possibility would be to create a model for the complete structure, and this is usually not desired since it may take a long time.

 

Using the Block Properties - Solver dialog box, the user can choose between two solver options, when performing a transient simulation:

 

1. The standard model represents any associated PEEC models by an RLC network, including loss mechanisms.

2. The dispersive model applies a model order reduction on any associated PEEC models, including loss mechanisms.

 

There are some further particularities of a CST PCB STUDIO block that should be mentioned for the sake of completeness:

For a CST PCB STUDIO block, a further navigation tree item called 'Info' is accessible. Clicking on this item opens a simple text box that contains information about the project that the block is associated with. The navigation tree does also contain a plot view of transfer impedances if those were calculated by CST PCB STUDIO™.

Some Details

After dropping this type of block inside the schematic view, the Import CST PCB STUDIO File dialog box is opened. There, you may browse for a CST PCB STUDIO™ project file. A PEEC or TL model that belongs to the selected project must also be available. This model may be created in CST PCB STUDIO™. If this model does not exist, the insertion of the block will fail. Note that the existence (or lack) of this model is announced inside the ’Import’ frame of the dialog.
 

Let us examine the contents of a CST PCB Studio file block’s property dialog box. Because this type of block provides no parameters, the initial page shown is the Block Properties - General page.

 

A CST PCB STUDIO file block is always frequency bounded. As usual, the limits are displayed in the Block Properties - General page. Furthermore, the file that the block refers to is displayed there. The block offers the usual features of File Blocks like browsing for a new file, editing the referenced project, choice of relative or absolute paths, updating file references and recovery of lost files.

 

If the PEEC or TL model for the associated project is outdated it will be automatically calculated during the execution of a task.
