Creating Your
Custom Data
Generators and
Checkers The data_gen_checker_top_40bits.v is the top level for the data
generators and checkers. If you would like to create your own data
generators and checkers, replace this module with your own module. The
data output of this module should be connected to the tx_datain port
of the transceiver instantiation (alt2gxb_6G_6250.v) in the top-level
design_s2gx_top_level.v
