) extends uvm_sequence #(REQ, RSP)
Methods
new()Construct the object.
do_write()Helper function which does a write given a register name and data to write.
do_read()Helper function which does a read given a register name.
do_write_read()Helper function which does a write and a read given a register name and data to write.
body()Base class functionality; find what sequencer we are connected to, and lookup a “counter” parameter.
new()Construct the object.
body()A sequence which calls the base class, then retrieves a list of all registers.

Methods

new()

function new(string name =  "uvm_register_sequence_base")

Construct the object.

do_write()

virtual task do_write(string register_name,
dataWidth_t data_to_write)

Helper function which does a write given a register name and data to write.

do_read()

virtual task do_read(string register_name,
output dataWidth_t data_read)

Helper function which does a read given a register name.  It returns the data read as an argument.
