Bug ID: 1506982144
IP: Stratix 10 External Memory Interfaces

Why is there a mismatch on the write and read data between the AXI bus interface and the Intel® Stratix® 10 MX HBM2 simulation model messages during simulation?

Description

The mismatch occurs because the write data from the AXI bus interface is going into the Intel® Stratix® 10 MX HBM2 IP's soft adapter and through the Universal Interface Block Subsystem before it reaches the Intel Stratix 10 MX HBM2 memory model. The "write data" bus value that is reported at the HBM2 memory model has been modified due to the data bus inversion (DBI).
