The basic pattern generator for 2.5 Gbps data rate is described in the following files:
<component_name>_basic_pat_gen_2g5.v[hd]
<component_name>_axi_pat_gen_2g5.v[hd]
<component_name>_axi_pat_check_2g5.v[hd]At present, the basic pattern generator has only one functional mode: generator. In the generator mode, the TX data is provided by the pattern generator with the RX Data being optionally checked by the pattern checker. Both the pattern generator and checker have a 32-bit datapath as the user side AXI4-Stream interface is 32 bits for 2.5 Gbps data rate.
