5.3.2. Timing Transfer for TDM Modes

There are three types of timing transfer in TDM modes.

Timing Transfer Description
Core-to-periphery transfer (TX side)

A synchronous transfer from the system clock with a flop in the core to the DIB clock with a flop in the periphery on the same die.

The Timing Analyzer in the Intel® Quartus® Prime software analyzes this path as a regular path.

Die-to-die transfer

Intel determines the timing closure for this path.

Periphery-to-core transfer (RX side)

A transfer from the DIB clock from the RX die to the system clock on the RX die.

For SYNC mode only: The Timing Analyzer in the Intel® Quartus® Prime software analyzes this path as a regular path.
