2 bit passwords
1 bit from door sensor on and off
1 bit switch monitor or not to monitor

outputs

led1 act as alarm when door is opened witout entering correct passwords i.e door sensor is set to 1

Re: FSL based home security system

Let me understand the problem.
If you open the door without entering a password, alarm1 will activate.
If after 10 seconds a valid password hasn't been set, alarm2 will activate also.
Is that correct?

What board are you using?

Yes that is what i want to implement.

I am implementating it on spartian II fpga

why do you need Spartan II for it? Yoy can use simple PIC MCU

It is a part of project and i am using fpga as i have to integrate various features

I have written some code but i am confused in two thinks how to synchornized with clock ie that my state changes on every posedge of clock and second how to reset by password to 00 on every state.
