Why does my E-Tile or H-Tile Transceiver Toolkit GUI crash when performing load-heavy tasks (e.g., AutoSweep, BER traffic tests on multiple channels simultaneously) when used with Intel® Stratix®10 or Intel Agilex® 7 FPGAs?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software versions 19.4 and later, you might see Transceiver Toolkit instability. This instability can make the tool vulnerable to crashing.

Resolution

To work around this problem in the Intel® Quartus® Prime Pro Edition Software version 19.4 and later, follow these steps:

1. Zip up all the files in $QUARTUS_ROOTDIR/bin64/jre64 to keep a backup of the OpenJVM 1.8, which ships with the Intel® Quartus® Prime Pro Edition Software.
2. Remove all the files after zipping them (you can leave the zip file in the folder).
3. Download an Oracle 1.8 JRE Java SE Runtime Environment 8u212 compressed file (.tar.gz), which can be found here:

4. Paste the contents of the JRE compressed file into $QUARTUS_ROOTDIR/bin64/jre64.
