I would say always use entity instantiation if you can; it’s neater and safer. But there are some situations where the synthesis tools force you to use component instantiation. For example, when instantiating something that isn’t VHDL in a VHDL file. That could be a netlist, a hard macr...
This is a vhdl code in Quartus , I really did everything to solve the problem but I keep got an error.. anyone can helped me Code: library ieee; use ieee.std_logic_1164.all; library adk; use adk.all; entity mux5_1_1wide is port ( a_input, b_input,c_input,d_input,e_...

then the signal is set at 0 if there is a connection on the instantiation then the value instantiated is used. Expand Post Like2 likes gsasvari (Member) 2 years ago Thank you all for the answers! Now I can go ahead and brave...

So, I want call function convert with out parameter data in left hand side on entity instantiation. In Quartus I got error: Error (10344): VHDL expression error at fifo_rl.vhd(198): expression has 2 elements, but must have 3 elements Error (10344): VHDL expression error at fif...
