2017.12.12 17.1 Made the following changes:

2017.05.30 17.0 Made the following changes to the user guide:
  • Removed links to the What assignments do I need for a PCIe Gen1, Gen2 or Gen3 design that targets an Intel® Arria® 10 ES2, ES3 or production device? answer. These assignment are already included in the 17.0 release.
2017.05.15 17.0

Made the following changes to the IP core:

  • Added option soft DFE Controller IP on the PHY tab of the parameter editor to improve BER margin. The default for this option is off because it is typically not required. Short reflective links may benefit from this soft DFE controller IP. This parameter is available only for Gen3 configurations.

Made the following changes to the user guide:

  • Updated PCI Express Gen3 Bank Usage Restrictions status. These restrictions affect all Aria 10 ES and production devices.
  • Added statement that Intel® Arria® 10 devices do not support the Create timing and resource estimates for third-party EDA synthesis tools option on the Generate > Generate HDL menu.
  • Added cross references to data alignment and timing diagrams for the Avalon® -ST interface.
  • Corrected definitions of rx_par_err, tx_par_err, and cfg_par_err. These errors are not recorded in the VSEC register. The VSEC register is not supported.
  • Corrected minor errors and typos.
2017.03.15 17.0 Rebranded as Intel.
2016.10.31 16.1

Made the following changes to the IP core:

  • Added final support for the 128-bit interface to the user application.
  • Added support for the Intel FPGA IP Evaluation Mode.
  • Added licensing requirement.
  • Changed timing model support from preliminary to final for most Intel® Arria® 10 device packages. Exceptions include some military and automotive speed grades with the extended temperature range.

Made the following changes to the user guide:

  • Corrected the number of tags supported in the Feature Comparison for all Hard IP for PCI Express IP Cores table.
  • Removed recommendations about connecting pin_perst. These recommendations do not apply to Arria® 10 devices.
  • Changed the recommended value of test_in[31:0] from 0xa8 to 0x188.
  • Added a note saying that all 4 PFs must be programmed to support a Maximum payload size value greater than 128 bytes.
  • Added -3 to recommended speed grades for the 125 MHz interface.
2016.05.02 16.0 Redesigned the SR-IOV bridge. The 16.0 SR-IOV bridge includes the following changes:

  • Fixed minor errors and typos.
2015.06.05 15.0 Added note in Physical Layout of Hard IP in Intel® Arria® 10 Devices to explain Intel® Arria® 10 design constraint that requires that if the lower HIP on one side of the device is configured with a Gen3 x4 or Gen3 x8 IP core, and the upper HIP on the same side of the device is also configured with a Gen3 IP core, then the upper HIP must be configured with a x4 or x8 IP core.

  • Added Enable Intel Debug Master Endpoint (ADME) parameter to support optional Native PHY register programming with the Intel System Console.
