Why does the Intel® Stratix® 10 E-Tile device transceiver not transmit or receive at the new data rate after using the E-Tile Native PHY IP Embedded Streamer to load a new configuration profile when using Intel Quartus® Prime Pro Edition software versions 18.1 to 19.1?

Description

Due to a problem in Intel Quartus® Prime Pro Edition software versions 18.1 to 19.1 the transceiver MIF files may not be updated after pressing the Generate HDL button in the E-Tile Native PHY IP Parameter Editor.

You may see one or more of the following symptoms in your design as a result of this problem.

The MIF streamer status bit (0x40141[0]) may remain stuck high instead of pulsing high.
The MIF streamer status bit (0x40141[0]) may never pulse high.
The transceiver is incorrectly configured resulting in unexpected transmit and/or receive behaviour.

Workaround/Fix

To work around this problem you can follow the sequence below.

1) Delete the E-tile Native PHY IP instance <ip_name> directory.

2) Open the E-tile Native PHY IP instance <ip_name>.ip Parameter Editor and generate the HDL.

3) Recompile the design.

This problem is scheduled to be fixed in a future version of the Intel Quartus® Prime Pro Edition software.
