Inputs Tab - 1.1 English - PG313

The Inputs tab of the Customize IP dialog box is shown in the following figure and allows the configuration of the input ports, and associated clocks.

Figure 1. Inputs Tab

AXI Inputs

Set the number of AXI inputs to this instance and configure each input. The configuration options are:

Connected To

AIE

From the AI Engine array.

PS Non-Coherent

From one of the non-coherent interfaces of the PS.

PS PMC

From the Platform Management Controller of the PS.

PS LPD

From the low power domain.

PL

From the programmable logic fabric.

PS Cache Coherent

From one of the cache coherent interfaces of the PS.

PS PCIe

From the PCIe® interface of the PS.

Parity

Enables parity checking of the connection from the AXI master to the NMU. Even parity is used. The available parity options are:

None

No parity checking

Address

AXI Address parity checking enabled

Data

AXI Data parity checking enabled

Address and Data

AXI Address and Data checking enabled

Mapping of the parity bits is described in the following table:

Table 1. NMU Parity Pin Mapping

NMU Pin	Direction	VNOC NMU		HBM NMU
		Width	AXI Signal	Width	AXI Signal
AXI AWADDR Parity	IN	8	AWUSER[17:10]	2	AWUSER[12:11]
AXI ARADDR Parity	IN	8	ARUSER[17:10]	2	AWUSER[12:11]
AXI WDATA Parity	IN	64	WUSER[127],WUSER[125],WUSER[123],WUSER[121].....WUSER[3],WUSER[1]	8	WUSER[15],WUSER[13]…..WUSER[3],WUSER[1]
AXI RDATA Parity	OUT	64	RUSER[127],RUSER[125],RUSER[123],RUSER[121],RUSER[119],....RUSER[3],RUSER[1]	8	RUSER[15],RUSER[13]…..RUSER[3],RUSER[1]
AXI WPOISON	IN	1	WUSER[0]	1	WUSER[0]
AXI RPOISON	OUT	1	RUSER[0]	1	RUSER[0]

Note: Parity checking is only available for inputs connected to PL. No parity checking is available from PS or AI Engine.

Inter-NoC Inputs

Specify inputs from other axi_noc instances using the Inter-NoC Interface (INI).

You can optionally set the INI Connection Strategy as follows:

Auto

IP integrator determines the correct strategy. This is the default setting.

Single Driver

Has a single driver and possibly multiple loads.

Single Load

Has a single load and possibly multiple drivers.
