This command sets a single interface property for an interface.
set_interface_property
Callback
availability
Main and elaboration
Usage
set_interface_property <interfaceName> <propertyName> <value>
Returns
String
Arguments
Example
interfaceName
The name of an interface that includes this property
propertyName
The name of the property whose value you want to set, which is ENABLED or
ASSOCIATED_CLK or a name from the Avalon Interface Specifications.
value
The value to set for the specified property
set_interface_property mm_slave linewrapBursts false
add_interface_port
This command adds a port to an interface on your module. As the component author,
you determine the name of the port. The port width and direction must be set by the
end of the elaboration phase. The port width can be set with one of the following
mechanisms:
1
■
A constant width or a width expression can be set in the main program
■
A constant width can be set in the elaboration callback
Without an elaboration callback, for static components quartus_map determines the
port width from the HDL
add_interface_port
Callback

Usage
add_interface_port <interfaceName> <portName> <portRole> [<direction> <width_expr>]
Returns

interfaceName
The name of the interface to which the port belongs.
portName
The name of the port that you, the component author, have chosen.
portRole
The role of this port within the interfaces. Port roles are referred to as signal
types in the Avalon Interface Specification. Refer to the Avalon Interface
Specifications for the signal types available for each interface type.
direction
The direction can be input, output, or bidir
width_expr
The port's width expression. In simple cases, this is just the width of the port in
bits.
