Maintain a FPGA project with Git is purely pain in ass But I am still going to do it

Gps PulsePerSec Pulse Tamed Timer

Usage

Basically, a taming_timing.v file contains the implement and benchmark of GTT, include it into your project and provide the clk and input signal:

  • GPS PPS pulse shall be feed to clk correct,
  • A 10M input clock shall be feed to clk in.

If the PPS pulse actual comes at 1Hz(But normally it is not) and clk is corrct:

  • the output time giving by epoch[31:0] port will increase as PPS comes.

  • The lock port will show if the internal counter is sync to PPS.

epoch set & reset port are not fully functioned right now, I'm still working on it

Still Under Construction
