描述

In the 2019.1 release, some devices are either not supported or only partially supported by the JESD204 IP.

The following devices are partially supported by the IP. The IP and example design will generate correctly if set to use GTHE4.

However the IP does not support selecting GTYE4 when customizing the IP either from the catalog or in IP integrator.

The following devices are partially supported by the IP.

The IP and example design will generate correctly if set to use GTHE(3/4) or GTYE(3/4) when customizing the IP from the IP catalog.

However the IP does not support selecting GTYE(3/4) when customizing the IP in IP integrator.

The following devices are partially supported by the IP.

The IP can only be used with "Shared Logic in the example design" selected and the example design will not generate.

The work-around for using these devices in Vivado 2019.1 is given below.

解决方案

For 2019.1, the devices listed in the tables above have limitations in terms of JESD204 IP support.

In all cases, the IP will appear as though it supports the device.

However, trying to select GTYE(3/4) will not be possible and the following actions will result in an error:

The work-around for the JESD204 core is as follows:

• Generate the JESD204 core with shared logic in the example design and then generate a JESD204_PHY core with the correct GT settings.
  Connect the two cores as directed in (PG066). The example design from a supported device can also be used for reference

Alternatively

• Use the JESD204C core with 8B10B encoding selected.
  In the 8B10B encoding mode, the JESD204C core is compatible with the 8B10B protocol.
  However the JESD204C core is not a drop-in replacement for the JESD204 core as it has a different register map
