6.2. DIB Intel® Stratix® 10 FPGA IP User Interface Signals

The DIB Intel® Stratix® 10 FPGA IP uses the DIB control, data and DIB pad signals.
Table 10.  Control Signals
Signal Width Direction Description
iopll_locked 1 Input

When you set the DIB Channel Type parameter to Standard Channel, this signal connects to locked IOPLL when using a bank with TDM.

This signal is not applicable if you select AUX Channel.

dib_ready_n 1 Output This signal goes low when the DIB channel is ready.
Table 11.  DIB Pad Signals
Signal Width Direction Description
dib_pad_0 24 Input/Output

DIB pads for bank 0.

The direction of this signal depends on the mode of I/O bank 0.

dib_pad_1 24 Input/Output

DIB pads for bank 1.

The direction of this signal depends on the mode of I/O bank 1.

dib_pad_2 24 Input/Output

DIB pads for bank 2.

The direction of this signal depends on the mode of I/O bank 2.

dib_pad_3 24 Input/Output

DIB pads for bank 3.

The direction of this signal depends on the mode of I/O bank 3.
