Pulse generator using 50MHz clock

[bharathkb]

Hi,
I am trying to implement a pulse generator that generates 6 pulses. us:micro seconds
Specifications: clock:50MHz
pulse width:10us and 15us
Pulse repetition time:150us

The requirement is that the first 3 pulses should be of pulse width 10us and the next 3 pulses should be of 15us.
Please suggest a suitable vhdl code.

Bharath,
Here is sample **broken link removed**.

In the above code it will generate ON/OFF pulse every 1 sec.

50MHz produce 20ns timing. To convert 20ns to 1sec, 50000000 counter is generated.

for your case, 10us/20ns= 500 counter , 15us/20ns = 750 counter.
