Creating a New Device

Creating a New Package

Enter a name and the number of pins. Package Type is IEC specific and can be neglected.

Click Next.

Defining Technologies

Enter a name and the number of blocks for each technology.

Outcome: the BOM is generated.

Toggle module display for editor to see Devices, DIEs and Package.

Setting Parameters

Set FIT fraction for Package or other parameters as needed:

Set Component Type for Total DIE or separately for each technology used.

Set Component Type for Total DIE or separately for each technology used.

Set FIT% for all Blocks.

Alternatively, check “Area based distribution”.

BOM Import

Create a new BOM and from the File menu select Import > BOM import.

Excel template:

Outcome: the BOM is imported.

You may add some parameters not defined in the Excel template.

Defining Soft Errors

In Document properties you may define additional types of error.

Soft errors can be applied to Blocks, for example, and FIT values can be edited from within the table.

Using Custom Failure Rates

Whilst catalogs subsumed under the System folder cannot be modified, it is possible to edit the Public structure, which enables working with customized failure rates.

To do so, start by adding your own subfolder to Public, i.e. right-click on Public and select New > Folder.

Next, associate your folder with a catalog of your choice, e.g., SN29500. To accomplish this objective, right-click your folder and choose New > Failure Rate Catalog (SN29500).

For the purposes of this example, we simply name the new catalog “SN”. It will be in evidence in the Catalogs tree as an element within your previously created folder:

The relevant SN29500-1 subfolder for semiconductors is 01. Integrated Circuits (part 2).

You now need to create a copy of this subfolder by dragging and dropping it onto your previously created Public folder:

Save your work. It is now possible to involve in your process customized elements thus set up. For example, you may wish to add to “01. Integrated Circuits (part 2)” (in your custom folder) another nested folder to define a anew Type, under which it is possible to subsume a Component:

If now you resume work on your system, the new component type will be available to your FIT calculation:
