connect between sub-blocks at the same and differentE component

[Altera_Forum]

Hi ,  

i want to connect the control signal - Seed_En (attached file) that his source block is LockStateMachine to :  a. The sub-blocks PN_transmitter at the same component - Rx .  do i need to define the instantiation of the Seed_EN at the Rx block or at LockStateMachine block ?  b. The sub-blocks PN_transmitter at different component - Tx .  do i need to define the instantiation of the Seed_EN at the Tx block or at LockStateMachine block ?   do i need to define output port to the component Rx and instantiate between the Seed_En and the new port ?  do i need to define input port to the component Tx and instantiate between the Seed_En and the new port ?   btw - every component and sub block is different file at the project and there is Top file that define the I/O 's and there is TestBench file  for the project for simulation.  Thanks .

Inside component "RX" you would write: 

 entity RX...   seed_EN_out : out std_logic; ...   architecture...  signal seed_EN : std_logic; begin ...  lock_unit : entity work.lockstatemachine  port map(...  seed_EN => seed_EN, ...  pn_unit : entity work.pngeneratorrx  port map(...  seed_EN => seed_EN, end architecture...

did you mean at the instantiate of : 

... lock_unit : entity work.lockstatemachine port map(... seed_EN_out => seed_EN, ... pn_unit : entity work.pngeneratorrx port map(... seed_EN_out => seed_EN, end architecture...  do i need to define seed_En as input port at the entities: lockstatemachine,pngeneratorrx ? ---------------------------------------------------------------------------------------------  At the second entity - Tx , do i need to define seed_En_in as input port and instantiate between the Seed_En and the new port ? Thanks .

seed_EN is juist a wire connecting the seed_EN_out ports of the two entites. It would be declared as an internal signal in the design file that instantiates the two entites.

o.k ,  

i will define seed_EN_out as output port from lockstatemachine , but should i define seed_En_in as input port at the entities:pngeneratortx,pngeneratorrx ?  and then instantiate : seed_EN_out => seed_EN_in ? if not , how will seed_EN be connection between lockstatemachine and the two entities ?
