Time to digital converter (TDC)

LogicPool (TDC)

This module is a software implementation, no need of hardware to work. The TDC will capture the time stamp of the input channels by rising edge so long the gate is activated. The maximal time resolution is 10 ns and can be changed through a programmable register, an external signal can be used as TDC clock too.

This module has a bus interface to connect with a FIFO, in this FIFO will be written the channel and time information of each rising edge, so long the gate is active.
