If a release note is not available for a specific IP core version, the IP core has no changes in that version. Information on the latest update releases is in the Quartus Prime Design Suite Update Release Notes.
The ATX PLL IP core only supports integer mode. It does not support fractional mode (unless in cascade mode).
Issue: ACDS 15.1 introduces a necessary fix for Arria 10 transceiver designs. This fix introduces a change that affects post-fit simulation for designs containing Arria 10 Transceiver Native PHY, Arria 10 Transceiver ATX PLL, Arria 10 Transceiver CMU PLL, and Arria 10 fPLL IP cores.
pll_powerdown is not connected for HSSI PLL IPs.
Workaround: Users requiring post-fit simulation of the transceiver PLLs in ACDS 15.1 need to disable the "Transceiver Reset Sequencer" for their design to produce a post-fit simulation netlist. However, this cannot and should not be used to produce the final bitstream for hardware. Hardware requires the "Transceiver Reset Sequencer" to be enabled.
To disable the "Transceiver Reset Sequencer" in the Quartus Prime software, add the following QSF to the Quartus Settings File for the project:
set_global_assignment -name VERILOG_MACRO "ALTERA_XCVR_A10_ENABLE_ANALOG_RESETS=1"
This will completely disable the reset sequencer in the design and restore the old behavior. This method does not allow post-fit simulation of the "Transceiver Reset Sequencer" logic.
Resolution: A modification to the PLL simulation models is planned for a subsequent release of ACDS 15.1 to remove the reset requirement.
pll_powerdown inputs to the Arria 10 Transceiver ATX PLL, Arria 10 Transceiver CMU PLL, and Arria 10 fPLL IP cores for Quartus Prime synthesis. As a result, the resulting generated post-fit simulation will not have a reset input connection for the PLL and post-fit simulation will likely fail.
Added an Advanced Parameters tab that displays the following values:
|Verified in Quartus II software v14.1.||-|
|The Quartus II software v14.1 requires that you specify a device if your IP core targets the Arria 10 device family. If you do not specify your target Arria 10 device, the IP Upgrade tool insists that your IP core requires upgrade but does not clarify the reason.||You must ensure that you specify a device for your v13.1 Arria 10 Edition or v14.0 Arria 10 Edition IP core variation and regenerate it in the Quartus II software v14.1.|
|Upgraded to support the new IP Catalog. For more information about the IP Catalog, refer to IP Catalog and Parameter Editor in Introduction to Altera IP Cores.||-|
|Added support for fractional mode. Fractional mode provides support for a wider range of output frequencies than integer mode. This feature is available under the Output Frequency tab.||-|
|Added support for Embedded Debug feature. This feature enables you to write to the PLL control registers and read from status registers for the PLL instances in the design. This feature is available under the Dynamic Reconfiguration tab.||-|
|Added the following presets for GT and GX
|Changed the documentation link in IP Parameter Editor to refer to the Arria 10 Transceiver PHY User Guide.||-|
|Enhanced user warnings and information messages.||-|
|Initial release for Arria 10 devices.||-|
