Arria 10 Transceiver ATX PLL IP Core Release Notes
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
Arria 10 Transceiver ATX PLL IP Core v15.1 Revision History
Table 1. v15.1 November 2015
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
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
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"
Resolution: A modification to the PLL simulation models is
planned for a subsequent release of ACDS 15.1 to remove the
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
Arria 10 Transceiver ATX PLL IP Core v14.1 Revision History
Table 3. v14.1 December 2014
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.
Arria 10 Transceiver ATX PLL IP Core v14.0 Revision History
Table 4. v14.0 Arria 10 Edition August 2014
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
Dynamic Reconfiguration tab.
Added the following presets for GT and GX
25781.25 Mbps Single Channel
Mbps Single Channel
Mbps xN Non-Bonded
Changed the documentation link in IP
Parameter Editor to refer to the
Arria 10 Transceiver PHY User Guide.
