Description

Refreshes the in-memory view of all of the properties, or specified properties, of the specified hw_mig objects with values read from the current hardware device.

The refresh command takes the values from the memory controller implemented on the hardware device, and populates them into the appropriate properties of the hw_mig debug core in the Vivado logic analyzer, or standalone Vivado Lab Edition.

At least one object is required. If properties are specified that do not exist in the object, that property will not be refreshed.

This command updates the properties on the hw_mig object, but otherwise returns nothing if successful. The command returns an error if it fails.

Arguments

-regexp - (Optional) The list of properties to refresh is defined using regular expression.

-properties <args> - (Optional) Refresh the specified property or properties of the hw_mig object. As a default behavior, if no properties are specified, all properties of the specified object or objects will be refreshed from the current values on the hardware device.
Tip: If a non-existent property is specified, that property is ignored.
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.
<hw_objects> - (Optional) Inputs can be any hw_mig, hw_device, hw_target, or hw_server object.
Note: The objects must be specified using the appropriate get_hw_xxx command, for instance get_hw_migs, rather than specified by name.

Example

The following example refreshes all of the properties of the memory IP in the Vivado logic analyzer with the properties from the current hw_device: 
refresh_hw_mig [lindex [get_hw_migs] 0]
