Hello guys,
I hope everyone doing alright, i got a project that i am starting to work with and want to get your advice.
I have laser pulses and i want the FPGA to count the time between two pulses .
in my mind and correct me if i am please, i will have convert the analog signal to digital signal in order to count the time from laser pulses.
i want to know if there is any guide or paper or sample code that my help me understanding and start doing my task
i hope i can get you help
have nice day

1. You need to confirm if the analog pulses can feed to FPGA directly firstly;
2. If item 1's answer is not, so you should shape your pulse before feeding to FPGA. You can refer CFD function.
3. After shaping, the pulse feed into FPGA, and you can measure the pulse by using fpga-based TDC. You can refer my blog

Overall, your task is typically of time measurement.
