i got the truth table i know how to know the SOP and produce it in forms 
of gates. But my lecturer wants us to create a vhdl and verilog code for 
the problem. Am new to verilog and am finding it difficult. Please i 
need help with the codes

I'm here to the rescue!

I can undertake your project for a minimal sum. Let me know if you are 
interested in order to discuss this further.

This is the testbench. You need to compile both files using Modelsim and 
run the simulation

"a3" could be optimized:

  a3 <= (p1 AND p2 AND p3) OR (p2 AND p3 AND p4);

Hey Valko,

do you waste your life solving computational tasks for free?

Geez.

Dear Marho, my job is done here.

Have a nice Modelsim (or GHDL) session!

Yeah, you too... Are you into this field? Which country do you live in? 
Can you share any samples (even screenshots) from your portfolio?

OFFTOPIC: I'm looking to hire someone for LLVM backend development. It 
will be a short 90-day task. Me and my cofounder can pay a reasonable 
sum, close to what you would get on Google Summer of Code (without the 
mentoring of course).

In case you are interested to discuss further on technical stuff. It 
will be a rainy weekend here so plans are basically to continue 
development. Fri-Thu will be sunny and best option for outdoor 
activities.

I mean Mon-Thu will be sunny :) Sorry for the OT post, still interested 
in discussing technical on VHDL for instance.

Hi Valko,

Thanks a lot, i have ran the vhd code on my modelsim and it compiled and 
is outputing waveforms. One last thing..i am feeling really backwards at 
the moment because i just got introduced to modelsim verilog and vdl 
coding. I know it sounds really selfish of me but please is there anyway 
you could help me with the verilog code for same project. CHeers

You might be able to help yourself:
http://www.syncad.com/verilog_vhdl_translator.htm

Google can suggest other tools which can translate VHDL to Verilog.
Since the code is not that difficult it shouldn't cause any troubles 
when you're using translating tools.

Good luck!

Hi Valko,

I think you should write the Verilog code for Marho.

Marho, if you want to roll your own, check out the vhd2vl free tool. It 
is capable of handling a certain VHDL subset, however you will have to 
make a second pass fixing any syntactical mistranslations.

Best regards

 I used the verilog_vhdl_translator to translate the Vdhl file to 
verilog. I tried compiling and i dont get any wave output on my 
modelsim. Not really to sure about the code maybe its not properly 
translated because when i compile it, it doesn't show any errors

You had to take my offer. Now you are spending the 2nd day in a row to 
resolve this simple task. I don't think you properly balance work for 
life.

Anyway, since I'm not getting not a single dime out of this, check out 
your testbench. Something is missing. Do you understand what is missing 
from there?

Hi Marho

collaborative culture is against Greek custom.

In Greece, everyone is on his own, unless he/she pays for "official" 
help. This is how things are since forever.

Best regards
Nikolaos Kavvadias
