hi everyone

i made same project on this thread but with differnce code my code like this

module Seven_Seg_Display_V2001 (

Here is the result of the simulation

i want to check it is correct or not
can u tell me if it not correct answer what is the right answer?
i hope to get any reply before 24 hour bec. it must be sumitted twm.

thankx

Since this is homework, it really should be in the Homework Help section.

Also, you need to show what work YOU have done to solve YOUR homework problem. We won't just do it for you.

What is preventing you from being able to determine whether your code is producing the correct results?

 

thank u for reply,
bec. this is first time to use verilog
i do not study it before but my teacher requirement to do it by using verilog

 

Let's take a step back. What result is your code supposed to produce?

 

it convert bcd to 7 segment
4 binry input 7 decoder output than it show on 7 segment like decimal number
0,1,2,3,4,5,6,7,8,9

+-a-+
f b
|-g-|
e c
+-d-+

 

And how is this supposed to be shown in the simulation results you posted?

 

this is my question

 

Well, how are WE supposed to know how YOUR simulation is supposed to show something?

If we came to you and said that we were putting together a simulation to test whether a BCD-to-7SEG encoder was working properly, what signals would YOU tell US should be in the simulation?

 

it show decimal nu. from 0 to 9
each signal one line
--0
----1
-------2
---------3
-------------4
----------------5
---------------------6
so on
^^

 

Do you have ten different signals?

You have a 4-bit input (the BCD value) and a 7-bit output (the signals to the 7SEG display).

Let's call the bits of the input V[3:0] wher V[3] is the msb and V[0] is the lsb.

Let's call the bits of the output Y[6:0] where Y[6] is the 'g' segment and Y[0] is the 'a' segment.

For the decoder you are trying to implement, is the output HI or LO for a segment that is supposed to be lit?

Can you prepare a truth table for what your input/output relationships should be?

DEC||V[3]|V[2]|V[1]|V[0]||g|f|e|d|c|b|a
0|||||||||||||
1|||||||||||||
2|||||||||||||
3|||||||||||||
4|||||||||||||
5|||||||||||||
6|||||||||||||
7|||||||||||||
8|||||||||||||
9|||||||||||||

Okay, so set up your simulation so that it shows these signals.

 

ok how?

 

it must change this part of my code ?



$monitor(" BLANK=%b, ZERO=%b,ONE=%b,TWO=%b, THREE=%b,FOUR=%b,FIVE=%b, SIX=%b,SEVEN=%b, EIGHT=%b,NINE=%b",BLANK,ZERO,ONE,TWO,THREE,FOUR,FIVE,SIX,SEVEN,EIGHT,NINE

How can we possibly tell you how to set up your simulation when we don't even know what simulator you are using? There are dozens of simulators out there. If you tell us exactly which simulation environment you are using, then MAYBE someone here might be familiar with it. But you best bet is to go through the tutorials that usually come with the simulator for Getting Started. They usually aren't very thorough, but should cover the basics that you need for this.
