Hey Jim,

Thanks for the info! I am planning on making one VC that encapsulates both tx and rx, but takes two transaction interfaces so that you can send and receive independently. Similar to how you mentioned in your first paragraph.

Due to how much the tx and rx need to talk to each other with regards to flow control and intialization, I am…[Read more]

variable RV:RandomPType;
variable b:std_logic_vector( 7 downto 0);

RV.Initseed(RV’instance_name);
