LogiCORE SPI-4.2 (POS-PHY L4) v6.0 - A Source core improperly segments the burst when SrcBurstMode=1

Description

General Description: 

When I use an SPI-4.2 v6.0 Source core with SrcBurstMode=1 and the source core goes out of frame, it begins transmitting training patterns on the credit boundary instead of the burst boundary. This violates the premise of the Burst FIFO (although it does not violate the SPI-4.2 specification). The correct behavior is to send the training on the burst boundary.

Solution

This issue will be addressed in the SPI-4.2 v6.1 release.
