Generating an ultrasonic (40 KHz) square pulse for a distance sensor with VHDL

May anyone give me a hint how to generate a square pulse with VHDL to transmit it in a transducer for a distance sensor. Thanks Francisco.

I is actually 50 MHz, yet I have a given clock divider so I have different possible outputs, such as: 1 MHz, 100KHz, 10KHz, 1KHz, 100Hz,and 1 Hz. Ok, Thanks
