// Description:
// A noc_shell interface to the backend infrastructure
//
// Parameters:
// - CTRL_CLK_IDX: The index of the clock that is used for the control interface.
// UHD will query this to generate a clock interface object for
// the register interface. Set to 0 to let UHD figure this out
// itself.
// - TB_CLK_IDX: The index of the clock that is used as the timebase for this
// block. UHD will query this to generate a clock interface object
// for the register interface. This allows converting real-valued
// timestamps into tick counts.
