Personally describing VHDL code for multiplexer can be quite difficult without prior knowledge. It takes many VHDLs to be a multiplexer.

we'll get 4 input mux cuz 2^4=16.... therefore the first 4 input mux has 16 o/p.. hence four-4 i/p mux are required to fill all 16 leads.
Write a program in c++ that take input in a integer matrix of size 4*4 and find out if the entered matrix is diagonal or not.
It tells you at the bottom of the screen: 4 Save''. This means press F4 to save your program and specify the file name. After that you can use F3 to load the program.

There are 4 main differences between C programming and VHDL programming. C is a mid-level language, while VHDL is a hardware description language. C can handle one type of instruction, while VHDL can handle two. C does not require as much resource usage as VHDL. C can be written only with logical thinking, but a VHDL programmer must understand hardware circuits.
8:256 decoder circuit can be implemented by using 4:16 decoder circuit
A 4-input decoder can produce (2^n) outputs, where (n) is the number of inputs. For a 4-input decoder, (n = 4), so the number of possible outputs is (2^4 = 16). Therefore, a 4-input decoder can generate 16 distinct output lines based on the 4 input combinations.
To create a 6 to 64 decoder using four 4 to 16 decoders and one 2 to 4 decoder, first, separate the 6 input bits into two groups: the upper 2 bits (let's call them A5 and A4) and the lower 4 bits (A3 to A0). Use the 2 to 4 decoder to decode the upper 2 bits, which will select one of the four 4 to 16 decoders. Then, connect the lower 4 bits to all four 4 to 16 decoders. The selected 4 to 16 decoder will activate one of its 16 outputs based on the lower 4 bits, resulting in a total of 64 outputs from the combination of the decoders.

Oh, dude, making a 6-to-64 decoder with 4-to-16 decoders is like building a tower of Legos with some missing pieces. You just gotta cascade the 4-to-16 decoders in a way that each output of the 6-to-64 decoder corresponds to a unique combination of inputs from the 4-to-16 decoders. It's kinda like solving a puzzle, but with electronic components.
Oh I had to change the settings on the decoder to send the signal as 4:3 instead of 16:9
Click on the decoder 4 times the type in 130928:):):):):) I hope this helped:):):)
It turned out to be very easy))) But I was thinking for a while to solve the problem... )))Ok. Lets say we have inputs S3..S0. Let S3 and S2 go to inputs of each of FOUR of decoders; and S1 with S0 go to the inputs of the FIFTH decoder. The four outputs of the FIFTH decoder go to enable lines of the four decoders. Voila! It might be confusing, but just draw the whole thing and you'll see. Now you just need to enable the fifth decoder... HA-HA!
To create a decoder with symbols, you need to assign a unique symbol to each input combination of the decoder. For example, in a 2-to-4 decoder, you could use symbols like A, B, C, and D to represent the output signals corresponding to the input combinations. By using symbols that are easy to understand and differentiate, you can effectively represent the decoder's logic and functionality.
Use two 2-4 decoders.
