Description

The ORION To Wishbone Block is a communication bridge that translates ORION request into Wishbone protocol for low-speed serial communication medium using Manchester (IEEE802.3) encoding scheme. The block provides an infrastructure to allow in-system programming (flash update) of a remote system.

Parameters

General Settings

Wishbone Address Width
Number of wishbone bridge	This is a non-modifiable parameter. It is being set to 64 by design.
Unmapped register group	These are non-modifiable parameters and are design-specific.
Wishbone Data Width
Number of replica
Trim Command from input stream	When enabled, it will remove the command header field from the input data stream. It should be noted that the ORION block has a similar parameter, thus if this is in the ORION block, the user should disable this field in the current block.
Sample Period	This is a Non-modifiable parameter.

Inputs

RegAccessIn	Communication input port. This port should be connected to the RemoteRegAccessDataOut output port on the ORION communication block.

Outputs

RegAccessOut	Communication output port. This port should be connected to the RemoteRegAccessDataIn input port on the same ORION communication block.
RxDecodingError	This status port indicates the communication error in the management of incoming data.

Characteristics and Limitations

This Block has no specific characteristics or limitations

Direct Feedthrough	N/A
Discrete sample time	N/A
XHP support	N/A
Work offline	YES
