4.17. Intel® FPGA PTC - Report Page

The Report page shows per-rail currents calculated by the Intel® FPGA Power and Thermal Calculator ( Intel® FPGA PTC).
Figure 27. 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.

Table 31.  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 Intel® 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 Intel® Agilex™ 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 Intel® 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 Intel® Agilex™ devices, or the sum of static, standby, and dynamic currents (for Intel® 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.
