NEC Infrared Transmission Protocol Simulation

Hi, how can I simulate a NEC Infrared Transmission Protocol precisely in a vector waveform file without doing it manually. 

 

This is the Infrared transmission done manually with the help of time bar. It’s long to do and not precise.

Logical '0' – a 562.5µs pulse burst followed by a 562.5µs space, with a total transmit time of 1.125ms 

Logical '1' – a 562.5µs pulse burst followed by a 1.6875ms space, with a total transmit time of 2.25ms

This kind of thing would be much easier to generate in an HDL testbench rather than a vector waveform

ok, I will try HDL testbench
