5.8. Intel® FPGA PTC - PLL Page

Each row in the PLL data entry page of the Intel® FPGA Power and Thermal Calculator (PTC) represents one or more PLLs in the device.

Supported PLL types are family dependent, as outlined in the PLL Page Information table.

Table 16.  PLL Summary Information
Column Header Description
Total thermal power (W) Reports the total thermal power (in W).
fPLL utilization Reports the percentage of fPLL utilization. (This field is available for Intel® Stratix® 10 devices only.)
IO PLL utilization Reports the percentage of I/O PLL utilization.
ATX PLL utilization Reports the percentage of ATX PLL utilization. (This field is available for Intel® Stratix® 10 devices only.)
CMU/CDR PLL utilization Reports the percentage of CMU/CDR PLL utilization. (This field is available for Intel® Stratix® 10 devices only.)
Power rails Indicated the voltage (mV), dynamic current (A), and standby current (A), for various power rails.
Table 17.  PLL Page Information
Column Heading Description
Entity Name Specify a name for the PLL entity in this column. This is an optional value.
Full Hierarchy Name Specify the hierarchical path relevant to this entry. This is an optional entry. When entering levels of hierarchy, the pipe character (|) denotes a level of hierarchy.
PLL Type Specifies the type of PLL, which may include the following:
  • Fabric-feeding IOPLLs
  • I/O bank IOPLLs
  • fPLLs
  • CMU PLLs
  • I/O PLLs
  • ATX PLLs
(The availability of some PLL types depends on the selected device.)
# of Instances

The number of logical PLL instances with this type, counter, voltage, and frequency combination.

Bank ID The I/O bank ID for this row. A bank location can be assigned to PLLs to change how the PLLs are placed, affecting thermals and utilization. (This column is available for Intel® Agilex™ 7 devices only.)
# PLL Blocks Enter the number of PLL blocks with the same combination of parameters.
XCVR Die ID

Specify the transceiver die on which PLLs on this row are located. This field is not applicable for I/O PLLs, nor fabric-feeding I/O PLLs.

# Counters Enter the number of counters of the PLL.
VCCR_GXB and VCCT_GXB Voltage Specify the voltage of the VCCR_GXB and VCCT_GXB rails. This field is not applicable for I/O PLLs, nor fabric-feeding I/O PLLs.
Output Freq (MHz) Specify the output frequency for CMU and ATX PLLs.
VCO Freq (MHz) Specify the internal VCO operating frequency for PLLs.
Total Power (W) Shows the total estimated power for this row (in W).
User Comments Enter any comments. This is an optional entry.
