Why does the Lauterbach memory watch window display inconsistent values ?

Description

Due to a problem in the Quartus II software version 13.0, the data display in the Lauterbach memory watch window is not consistent due to an arbitration logic bug that causes Nios II JTAG Debug RAM accesses from JTAG to fail.

Resolution

This problem is fixed beginning with the Quartus II software version 13.1.
