Hi!

A am newbie with VHDL code programming for FPGA and I need some help.


I have simulation described on the blackboard. Here are described two variants:

Is it possible to write a code to FPGA based only on this?

Could you tell me as simple as it possible how to make it?
Co przedstawiają rozrysowane dwa warianty?
What does two variants show? (is it counter, register, ...?)
Czy w każdym wariancie są po 3 czy 4 sygnały? (do czego jest podłączony sygnał DATA?)
Does in each variants there are 3 or 4 signals? (what does DATA signal connected to?)

I work with Nexys™3 Spartan-6 FPGA Board.



Sorry if I wrote it in a wrong place but, it is very important for me.

Thank for reply!

 

I don't see very well. Draw the waveforms in Paint with the brush.

 

This one is the most important to me

 

Why did you draw with blue there? It has some meaning?
I see that the Data signal is sensible to negative edges in the BCX signal.

And on how many bits is DATA? And what is with the LSB and MSB there?

That drawing is all the information that you have?

 

I have PIN's arrangement too but it is not about it here I suppose.

I googled some VHDL examples with simulations: http://home.agh.edu.pl/~sglab/Technika cyfrowa/4_LicznikiRejestry/PrzykladyVHDL.pdf
Example nr 4 looks a little bit similar to this, but as I said I have just a little knowledge about it so can be wrong.

 

Which signals are inputs and which are outputs?

What is this bottom line with KL and KP all about?

It looks like your data consists of two words transmitted little endian. It also looks like if your WS (Write Strobe?) is 2N clocks long that you transmit/receive N+1 data words.

As this is Homework Help (and not Homework Done For You) you need to show your best attempt to solve your homework.

 

Its done, topic can be closed. You didn't have helped me at all !

 

Well, since you apparently expected someone to just work your homework for you with not show of effort on your own behalf, not even so much as to simply answer some basic questions about what your signals are, you didn't have much right to expect much.

 

Neither this thread could give him the answer ........

Yep. Probably found (or paid) someone somewhere to do it for him.
