@shimaz 

 This looks like an initial course assignment...     --- Quote Start ---   im doing a project on MM74HC154 FPGA 4-to-16 line decoder   --- Quote End ---     You can specify this as a schematic, VHDL or Verilog. Here is (one of the many possible) way(s) how you can do this in Verilog...      module MM74HC154(a, b, c, d, g1, g2, out); input a, b, c, d, g1, g2; output reg out; integer i; always @(a, b, c, d, g1, g2) if (g1 || g2) out = 16'bzzzzzzzzzzzzzzzz; else for (i = 0; i < 16; i = i + 1) out = ({d, c, b, a} == i) ? 1'b0 : 1'b1; endmodule  Have fun learing FPGA design.

thanks friend.. 

is this coding for verilog or VHDL... your dam good in programming..how can i learn programming...  waitng for your repy  shimaz

[Altera_Forum]

This is Verilog. There are many verilog tutorials on the web (http://lmgtfy.com/?q=verilog+tutorial).

[Altera_Forum]

sanmao your helping me a lot..i dont know how to thank you..ill write about you in my preface of the project 

how about the VHDL codings...

[Altera_Forum]

There are also many vhdl tutorials on the net (http://www.lmgtfy.com/?q=vhdl+tutorial).

[Altera_Forum]

can you give me the exact link for the vhdl

[Altera_Forum]

If you are new to VHDL the best is to buy a good book. This is important as designing hardware in VHDL or Verilog is quite different than programming in C/C++ or Java. 

 There are many good books out there on VHDL and Verilog.   If you are interested in learning VHDL, I can recommend : "the designer's guide to vhdl (http://www.ashenden.com.au/vhdl-book/dg3e.html)" from Peter Ashenden.

in this book do i get the information to do the verilog programing for MM74HC14 FPGA4-16 decoder ..im extremly sory for trubling you...hope you wont mistake me

[Altera_Forum]

You may not find the exact code for what you are looking for, but at least you'll learn how to do it. It's not that difficult.

im trying to simulate in vhdl since 4th of july 2009..i dnt no why im nt getting the exact output as schematic simulation..im mently failed for this..

[Altera_Forum]

What output do you get now and what do you expect to get?

[Altera_Forum]

im getting a different wave form of vhdl compaire to the wave form of shematic diagram verilog program..why im nt getting the output as same when i do my vhdl programming for mm74hci54 4-16 line decoder....hope you will help me,, 

  regards   shimaz

Show us your code and we could help you

[Altera_Forum]

i have send my vhdl coding to ur inbox..check it tel me the wrong where i have done,and hope u vl correct me

[Altera_Forum]

I can't see anything wrong with your code... What does the simulation output look like?
