First implement each of these functions, one at a time.

Then figure out how to select between the 11 functions.

 

one step at a time.

Summary:
1. Read the manual or user guide. Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts. If I write a good post, then I have been good for nothing.

You are new to digital logic design, correct?

And new to FPGA design?

And Verilog or VHDL coding?

 

Just implementing a single logic gate will be a milestone.

Then implement a function.

Then several functions.

Then a system.

 

If you try to do everything at once, how do you know where to start?

Verilog

OK, I see you're adopting the 'one step at a time' approach which I've been pushing.

 

Here are the other two questions I asked.  I'll let you decide which one of these to answer in your next post.

You are new to digital logic design, correct?

And new to FPGA design?

And Verilog or VHDL coding?

  • Do you understand the logic functions described in the exercise?
  • For each of the logic functions in the exercise, could you embody the function in Verilog?  If yes, please post your Verilog implementation of each of these logic functions (individually).

These are 2 good "first steps" on the way to completing the exercise.
