Entering FIDES COTS Boards
The following table describes the part parameters required for a COTS (commercial, off-the-shelf) board when a FIDES 2009 model is selected for the calculation. Only FIDES 2009 models support this FIDES part category. These FIDES models supports four COTS board subcategories:
Central Digital Functions
Common Functions All Boards
Inputs Outputs
Peripheral Digital Functions

Type
Choice List [Parts Count and Families Count also]
Required by all but the Common Functions All Boards subcategory.
The type of board. Choices vary by subcategory.
# of Bits
Integer [Parts Count and Families Count only]
Required only for some types of the Central Digital Functions subcategory.
The number of bits in the memory device. This parameter is used in conjunction with Units to enter the memory device bits.
Units
Choice List [Parts Count and Families Count only]
Required only for the some types of the Central Digital Functions subcategory.
The units for the # of Bits value. Choices are:
b (bits)
Kb (1024 bits)
Mb (1,048,576 bits)
Gb (1,073,741,824 bits)
The default is Kb. However, you can enter the unit in many ways. For example, for a 1-kilobit memory chip, you can enter a 1 for # of Bits and select Kb for Units, or you can enter 1024 for # of Bits and select b for Units.
Board Type
Choice List [Parts Count and Families Count also]
Required only by the Common Functions All Boards subcategory.
The central digital functions of the board. Many choices are available.
Board Length Override
Real (cm) [Parts Count and Families Count also]
Required only by the Common Functions All Boards subcategory.
The length of the device in centimeters.
Board Width Override
Real (cm) [Parts Count and Families Count also]
Required only by the Common Functions All Boards subcategory.
The width of the device in centimeters.
# of Parallel Buses
Integer [Parts Count and Families Count also]
Required only by some types of the Inputs Outputs subcategory.
The number of shared channels that transmit data over several wires simultaneously between components.
# of Lines per Bus
Integer [Parts Count and Families Count also]
Required only by some types of the Inputs Outputs subcategory.
The number of wires or lines per bus.
# of Analog IO Lines
Integer
Required only for the some types of the Inputs Outputs subcategory.
The number of analog input and output lines.
# of Serial Interfaces
Integer
Required only by some types of the Inputs Outputs subcategory.
The number of serial interfaces.
Quantity
Integer
Required only for some types of the Inputs Outputs subcategory.
The number of inputs and outputs for the device.
