4.7. Intel® Stratix® 10 EPE - PLL Worksheet

Each row in the PLL worksheet of the Early Power Estimator (EPE) for Intel® Stratix® 10 devices represents one or more PLLs in the device.

For Intel® Stratix® 10 devices, the supported PLL types are IOPLL, fPLL, ATX PLL, and CMU PLL.

Table 11.  PLL Worksheet Information
Column Heading Description
Module Specify a name for the PLL in this column. This is an optional value.
PLL Type Specifies the type of PLL. Intel® Stratix® 10 devices have I/O PLLs, fPLLs, CMU PLLs, and ATX PLLs. CMU PLLs and ATX PLLs are for L-tile and H-tile transceiver use exclusively. (E-tile transmitter PLLs are included in the XCVR worksheet and are not included in the PLL worksheet.)
# 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.
# Counters Enter the number of counters of the PLL. For fPLL, this includes C counter, L counter, and feedback. This field is not applicable for ATX PLLs and CMU PLLs.
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.
Output Freq (MHz) Specify the output frequency for CMU and ATX PLLs.
VCO Freq (MHz) Specify the internal VCO operating frequency for fPLLs and I/O PLLs. When using an fPLL as a transmitter PLL for XCVR channels, the VCO frequency has to be such that the required fPLL output frequency can be achieved using a legal value of the counter used for HSSI clock output.

You can find the VCO frequency (in Hz) in the Intel® Quartus® Prime Compilation Report. In the Compilation Report, select Fitter > Plan Stage > HSSI Transmitter PLL > vco_freq for each fPLL instance.

Total Power (W) Shows the total estimated power for this row (in W).
User Comments Enter any comments. This is an optional entry.
