64 bit FPGA tick-counter

Status: New
by Active Participant MarcoMauri on ‎06-16-2010 05:20 AM

The Tick Count function in LabVIEW FPGA can represent time periods with tick count accuracy of up to 2^32 clock cycles, that is (using the standard 40 MHz FPGA clock) about 107 seconds.

Sometimes I need to handle longer time spans, and I use this example.


I suggest to implement a built-in 64-bit tick counter.

A direct 64-bit clock will be very much needed. Kudos!!

i like the idea, but i think we should take it a step further and allow the user to wire a constant 'max count' into the node. the internal counter can then be optimized to use the fewest bits necessary to meet that criteria.

This is useful regular labview too. A 50 day overflow is too short.
