Hi, I am looking to control a H-bridge with a PWM which I have generated in my code, however I am clueless on how to include a dead timing in the PWM. I need a deadtime of 750ns on the on-time and 1us off time. Thanks.

How about a deadtime driver? Haven't checked your code, though there are some driver ICs on the market with adjustable deadtimes. Cheers,

Unfortunately the code is in VHDL, is there a way to modify it to verilog please? as I am working with verilog.

There are some free VHDL to Verilog translators out there, just google for it. But Lothars sample isn't that big, it is no biggie to do that from hand, and have then the benefit to understand how it is working.
