2014.2 AXI Traffic Generator- AXI 4K boundary limitation not honored for some configurations


The 4K boundary cross limitation in the AXI protocol is not respected by the AXI Traffic Generator (ATG) in Advanced mode for some configurations.


If the starting address provided in CMDRAM is not burst length aligned, there are some configurations where the address generated in advanced mode will not honor the 4KB boundary limitation of the AXI protocol.

The affected configurations are:

  • op-repeat operation (with Increment address selected)
  • op-fixedrepeat-delay (with increment or random address generation selected)

This is fixed starting in Vivado 2014.3.
