hello,can anyone give me the vhdl source code of fire detection system/fire alarm system especially for high rise building?
This is among the requirement :-
according to my "fire detection system for tall building" project by using Spartan 3E FPGA, the vhdl program need to include all of dis specification:-
First of all, we 'll put sensor/smoke detector each floor in the tall building.
1) alarm 'll activated if the sensor/smoke detector sense a fire
2)at the same time, the actuator will activate in order to control such a elevator and any other machines in the building.
3)the controller will display which floor caught by fire and the sensor/smoke detector initial or current temperature.
4)If there is false alarm, we can stop it by push the 'reset' button .
Hopefully u will help me in order to design the program....PLZZ....

entity alarm_system is
clk: in std_logic;
rst: in std_logic;
sensor: in std_logic_vector (5 downto 0);
alarm: out std_logic;
display: out std_logic_vector (7 downto 0)
architecture rtl of alarm_system is
process (clk, rst) begin
if (rising_edge(clk)) then
if (rst = '1') then
alarm <= '0';
actuator <= '0';
display <= (others => '0');
alarm <= alarm_f(sensor);
actuator <= actuator_f(sensor);
display <= display_f(sensor);

I wouldn't put too much stock in the design above:
-it lacks any concept of a state variable implementation
-it apparently was not 100% successful with its intended tounge-in-cheek style
See the URL provided above from more explanation.

If you are interested in learning more about the design considerations for an elevator system, you may find this useful:
http://courseware.ee.calpoly.edu/courseware/ee319/notess98.html (Notes on the evelator problem)
But again, I suspect nobody here wants to do anyone's homework. You may get some valid input if you:
-reviewed the problem
-thought about possible implementations
-attempted a design
-asked a few specific questions on issues
That is completely different than walking into a forum intended for user interaction and expecting someone to hand you a working solution with no effort on your part.
These type of problems, while contrived, usually exist for a reason - such as developing problem solving skills and weeding out those unwilling or unable to do the required work.

My name is Irinel. I am from Romania, student of UPG PLoiesti university. I need a project in Vhdl to commnad an ascensor(elevator).
Please help me! i don't have time to work a lot in vhdl because of my job and i need this project to be addmited on to exam. it don't have to be fully functional, just to be.
if you can mail me, the mail is: firstname.lastname@example.org

I suspect we all have busy lives and things we would like with little effort.
Please reread my previous post above on why you are unlikely to get the help you are looking for.
