The VHDL code for declaring a vector signal that can hold zero bits (an empty range): signal MySlv : std_logic_vector(-1 downto 0); Exercise In this video tutorial, we will learn how to declare std_logic_vector signals and give them initial values. We also learn how to iterate over...
signal INT_SIG : std_logic; begin U0 : PULLUP port map (O => INT_SIG); -- Infer tri-state buffers INT_SIG <= INBUSA(0) and SIGA(0) when (EN(0) = '1') else 'Z'; INT_SIG <= INBUSA(1) and SIGA(0) when (EN(1) = '1') else 'Z'; INT_SIG <= INBUSA(2) and ...

When using component instantiation , we must define the component before using it in the code. We can either do this in a separateVHDL packageor before the main code (in the same way as a signal). The code snippet below shows the syntax we use to declare a component in VHDL. The comp...
Port map is the part of the module instantiation where you declare which local signals the module’s inputs and outputs shall be connected to. In previous tutorials in this series we have been writing all our code in the main VHDL file, but normally we wouldn’t do that. We create ...
How I can to declare the signal xdataout_preprebuffer? the errors thrown by analysis & elaboration stage were these Error (10381): VHDL Type Mismatch error at Naive_RNC_problem.vhd(235): indexed name returns a value whose type does not match "Generic_ARRAY_type...
Hm. When i simply use RAM_integer_array in bla instead of sub_RAM_integer_array Quartus complains with: Error (10482): VHDL error at bubb.vhd(153): object "RAM_integer_array" is used but not declared File: c:/blubb.vhd Line: 153 So i think that i ha...

I want to force some internal signals in DUT. If I put the internal signals in a interface, can I use like " assign if.internal = 1’b1 " ? Does this value have a conflict with real internal value? I mean the signal “internal” will have two drives. Thank you so much! Junben...
Based on how the logic primitives are configured, custom logic is applied to selected input signals from inside a Control Peripheral resulting in output signal that is then injected back into a selected spot inside the Control Peripheral. Note, that the original input and output signals that ...
