Vhdl code for 1 to 2 demux
- 5. Implement 4 to 1 multiplexer using 2 to 4 decoder and external gates. WEEK 10 Comparators and code converters 1. Write VHDL code and simulate 1 bit equality comparator. 2. Write VHDL code and simulate 4 bit comparator. 3. Write behavioral VHDL code to convert an N bit binary number into an equivalent grey code. Use for loop. 4.
- The objectives of this lab were for us to become more adept at creating VHDL code for basic digital design devices; while demonstrating a more in-depth knowledge using the DE-1 board (Kelly, 2013). PROBLEM STATEMENT: For the third lab I was to implement VHDL code for the four attached diagrams shown below.

- completion, the logic 1 is routed by the Multiplexer to the clock input of the 2-it counter. The counter on receiving logic 1 increments its count to 01, which selects I1 input of the Multiplexer
- Let’s take a look at a 5:1 multiplexer and examine the alternatives that must be considered. The VHDL looks very simple, but are you aware of what this will really X-Ref Target - Figure 1 Figure 1: 4:1 Multiplexer Using Dedicated Slice Multiplexer X-Ref Target - Figure 2 Figure 2: 8:1 Multiplexer Using Two Slices D3 D2 D1 D0 Slice MUXF5 LUT3 ...
- The VHDL source code is shown in Fig. 1 and the schematic automatically generated by the synthesis tool is shown in Fig. 2. The input to this module is the 6-bit instruction opcode, OP(5-0). The language support for standard logic vectors or arrays of bits, such as OP, greatly simplifies coding of the VHDL model.
- type matrix is array (natural range <>) of std_logic_vector (m-1 downto 0); end my_data_types; 2. I have re writed the main code, so n is the size of the selector in bits i.e. if you define n=2, the selector will have 2 bits lenght so we will have 2**n inputs, in this case : 4 inputs . 3.
