4.16. Intel® FPGA PTC - Report Page

The Report page shows per-rail currents that the Intel® FPGA Power and Thermal Calculator (PTC) calculates.
Important: The Report page is for determining how much current each rail must be able to handle. Some of the power savings shown on pages, like Static Power Savings and Smart VID Power Savings, could come from different voltage rails for different devices, and because of this reason, the total power each rail must be able to deliver is higher than the total power the device uses.
Figure 56. Report Page of the Intel® FPGA PTC


The Report page provides current requirements for each voltage rail, expressed in terms of static current, dynamic current, and total current.

There is a minor difference in the format of the Report page between Agilex™ FPGA portfolio and Stratix® 10 device families:

  • For Agilex™ 5 and Agilex™ 7 device families, every row displayed in the Report table represents a corresponding voltage rail.


  • For Stratix® 10 devices, different sections of the table are preceded by an empty row. For example, an empty VCC row introduces the VCC section of the table, an empty VCCIO row introduces the VCCIO section, and so forth.


For the Power and Thermal Calculator Report table, you can press the F5 key to resize the rows to be the same height as other rows.

Table 40.  Current and Power Regulator Requirements Per Voltage Rail
Column Heading Description
Rail Name of the voltage rail.
Voltage (mV) Rail voltage.
Static Current (A) Indicates the component of current consumed from the specified power rail whenever the power is applied to the rail, independent of circuit activity (in A). This current is dependent on device size, device grade, power characteristics and junction temperature.
Standby Current (A) Indicates the component of active current drawn from the specified power rail by all modules on all pages, independent of signal activity (in A). This current is independent of device grade, power characteristics and junction temperature. Standby current includes, but is not limited to, I/O and transceiver DC bias current. Device size has only a small impact on transceiver DC bias current. (This column applies only to Stratix® 10 devices.)
Dynamic Current (A) Indicates the component of active current drawn from the specified power rail due to signal activity of all modules on all pages (in A). This current depends on device size, but is independent of device grade, power characteristics and junction temperature.
SmartVID Current Savings (A) Indicates the total current saved from the specified power rail due to SmartVID savings (in A). (This column applies only to Agilex™ 7 devices.)
Total Current Before SmartVID Savings (A) Indicates the total current consumed from the specified power rail before SmartVID savings (in A). The sum of static, standby, and dynamic currents. (This column applies only to Stratix® 10 devices.)
Total Current (A) Indicates the total current consumed from the specified power rail (in A). For devices and rails supporting SmartVID, this column shows total current after SmartVID current savings; otherwise, the current reported in this column should equal the sum of static and dynamic currents (for Agilex™ FPGA portfolio devices) or the sum of static, standby, and dynamic currents (for Stratix® 10 devices).
Recommended Margin Indicates the recommended margin on total current for regulator sizing. The recommended margin on the Vcc rail is calculated based on the ratio of dynamic to static power.
