Tag: vhdl, verilog. I have used VHDL all my life and only been using Verilog for a short time, I have to create a logic in Verilog for a very large array and assign it to 1 or 0 depending on the condition of an input. Here is my VHDL code. if (data_track == '1' ) then my_array (MAX-1:MIN) <= (others=> '1'); VHDL signal assignment with the OTHERS keyword I'm not sure I'm posting this in the right place but I want to assign an unsigned or std_logic_vector to the same type of a larger size. Input is 8 bits wide, outputsignal is 32 bits wide and I want to assign inputsignal(7 downto 0) to outputsignal(23 downto 16) with all other bits (31 downto 24 and 15 downto 0) in output being '0'.

In this case, there is no need to write twice the same module. It should be possible to parameterize the component during the instantiation. The line containing 'others' is required by VHDL to take care of any logic combination that is not taken care of by the preceding statements. This allows for any states besides logic 0 and 1 levels, such as high impedance signals - Z. Note that single signals are assigned logic values by using single quotes, e.g. '0'.

We can collect any data type object in an array type, many of the predefined VHDL data types are defined as an array of a basic data type.

VHDL Example Code of Signed vs Unsigned. Signed and unsigned are the types that should be used for performing mathematical operations on signals. This example shows how to use them to do addition, subtraction, and multiplication. Code is free to download.

Here is my VHDL code. if (data_track == '1' ) then my_array (MAX-1:MIN) <= (others=> '1'); else my_array (MAX-1:MIN) <= (others=> '0'); end if; MAX and MIN are parameters for the block, set during the synthesis depending on the type of system we are accessing.

Therefore, it is good practise to use an others branch which captures these states. As we talked about in the post on sequential logic in VHDL, the all keyword used in the process declaration was introduced in VHDL-2008. When using a standard prior to this, such as VHDL-93, we need to include all the inputs in the sensitivity list.
