5.3. Intel® FPGA PTC - Main Page
The required parameters depend on whether the junction temperature is manually entered or auto computed.
|Family||Shows the device family selected at startup, either directly or through the imported file.|
Select your device. Larger devices consume more static power and have higher clock dynamic power. All other power components are unaffected by device selection.
The parameter and value table on the right side of the PTC main page displays specifications of the currently selected device.
Select the combination of Operating Temperature, Speed Grade, and Power Option used. Refer to the device datasheet for available combinations.
Select the device package. Larger packages provide a larger cooling surface and more contact points to the circuit board; thus they offer lower thermal resistance. Package selection does not affect dynamic power directly.
Select typical or maximum power. There is a process variation from die-to-die. This variation primarily affects static power consumption. If you choose Typical power characteristics, estimates are based on long term projections of average power consumed by typical silicon. For FPGA board power supply design and thermal design, choose Maximum for worst-case values.
Note: Typical power characteristics should not be used for regulator sizing or thermal analysis; use Maximum power characteristics for these activities.
|VCC Voltage (mV)||(This field appears in the Intel® Stratix® 10 PTC only.)|
The Thermal Analysis section displays the junction temperature (TJ) and other thermal parameters, depending on the thermal analysis mode.
|Calculation mode||Specifies the calculation mode for the thermal solver to use. The available choices are:
|Junction temperature, TJ (°C)||Specify the junction temperature for all dies in the package. This field is available when you select Use a constant junction temperature as the Calculation mode.
In this mode, the junction temperatures for all dies in the package are assumed to have the specified value. To automatically compute junction temperatures, select one of the other options in the same field.
