`uvm_do (seq/item) On calling this macro, create, randomize and send to the driver will be executed

`uvm_do_with (seq/item, constraints) It is the same as `uvm_do but additionally, constraints can be defined while randomizing

`uvm_do_pri(seq/item, priority) It is the same as `uvm_do but additionally, the mentioned priority is considered.

`uvm_do_pri_with(seq/item, constraints, priority).  It is a combination of `uvm_do_with and `uvm_do_pri

`uvm_create(seq/item) This creates a sequence or item.

`uvm_send(seq/item) It directly sends seq/item without creating and randomizing it. So, make sure the seq/item is created and randomized first.

`uvm_rand_send(seq/item) It directly sends a randomized seq/item without creating it. So, make sure the seq/item is created first.

`uvm_rand_send_with(seq/item) It directly sends a randomized seq/item with constraints but without creating it. So, make sure seq/item is created first

`uvm_send_pri(seq/item, Priority) It is the same as `uvm_send but additionally. priority is also considered.

`uvm_rand_send_pri(seq/item, Priority) It is combination of `uvm_rand_send and `uvm_send_pri

`uvm_rand_send_pri_with(seq/item, Priority) It is a combination of `uvm_rand_send_with and `uvm_send_pri.
