1.The Aurora 8B/10B core provides a light-weight shim to interface to any existing LL based interface. The shims are delivered along with the core.
2.See This Figure for the emulation of an LL Aurora core from an AXI4-Stream Aurora core.
3.Two shims <component name>_ll_to_axi.v[hd] and <component name>_
axi_to_ll.v[hd] are provided in the src directory of the AXI4-Stream Aurora core.
4.Instantiate both the shims along with <component name>.v[hd] in the existing LL based design top.
5.Connect the shim and AXI4-Stream Aurora design as shown in This Figure.
6.The latest AXI4-Stream Aurora core can now be used with any existing LL design.
