Entering PRISM Integrated Circuits
The following table describes the part parameters required for integrated circuits when PRISM is the selected calculation model. This model supports all but the following subcategories of integrated circuits:
Custom
SAW - Surface Acoustic Wave.
Parameter
Type
Description
Year of Manufacture
Integer
The four-digit year in which the device was manufactured (such as 1998 or 2004). The default is the current year.
Package Type
Choice List
Indicates how the device is packaged. Choices are:
Hermetic
Non-Hermetic
Junction Temp Override
Real (Degrees C)
For a PRISM integrated circuit, this is the only temperature field available. If you enter a value for this parameter, this value is used for failure rate calculations in place of the PRISM temperature calculation. For more information, see PRISM Quality Levels.
