Verilog HDL long delay generation

[Dino1400]

I need to generate a long delay without using # , wail or for……….
Maybe A function that i will call once for a small delay say 5min or four times for 20 min
im looking for a long dealy
Any ideas please

verilog synthesizable long multiple delays

You can use a very long counter.

 

[Dino1400]

you mean like a 1024-counter, but i need about 5-different delays should i use 5 counters

 

[shaiko]

not necessarily a 1024-counter
The exact width shall be determined by the required delay and your system clock.

You don't have to use 5 different counters.
Set the counter width according to your longest delay.

The shorter delays will be activated when your counter reaches the desired vaule.

say we have a 100KHz clock how can generate a 5 minute delay without having a very long counter that may stop at all one's 111111111111111111111

get me start in here im really confused please.

Suppose your longest delay is toggled at :
111111111111111111111

The next shorter delay can be toggled at :
011111111111111111111

You can, but you don't have to use 2 seperate counters...

I don't speak Verilog very well - I can show you the VHDL code if you'd like.

thank very much I appreciate you help
