Detailed Description

Visitor for determining target device type of a Virtex-5 bitstream.

This visitor is derived from V5BitstreamSyntaxChecker, because when visiting a bitstream and trying to detect its target device type this bitstream has to be at least syntactical correct. The detection itself relies on the presence of a write into the IDCODE register, which tells the ID of the device the bitstream is for. If multiple IDCODE writes are present, thats no problem, unless they all write the same device ID; otherwise an exception will be thrown.

DeviceID::ID_t V5BitstreamDeviceDetector::deviceID ( ) const

Gets the detected device ID.

This method will return 0, if reset() was called directly before; or if no IDCODE command was found in the visited bitstream.

Returns:: The device ID.

void V5BitstreamDeviceDetector::reset ( )

virtual

Resets the syntax checker and the device ID.

Reimplemented from bil::V5BitstreamSyntaxChecker.

Definition at line 26 of file V5BitstreamDeviceDetector.cpp.

void V5BitstreamDeviceDetector::visit ( const Type1Packet & type1Packet )

virtual

Checks a Type1Packet packet for device ID data.

Parameters:

type1Packet Type1Packet instance to be visited.

Exceptions:

.

Reimplemented from bil::V5BitstreamSyntaxChecker.

Definition at line 33 of file V5BitstreamDeviceDetector.cpp.

void V5BitstreamDeviceDetector::visit ( const Type2Packet & type2Packet )

virtual

Checks a Type2Packet packet for device ID data.

Parameters:

type2Packet Type2Packet instance to be visited.

Exceptions:

.

Reimplemented from bil::V5BitstreamSyntaxChecker.

Definition at line 40 of file V5BitstreamDeviceDetector.cpp.

void V5BitstreamDeviceDetector::checkDeviceID ( const Type2Packet & type2Packet )

protected

Tests if packet contains a device ID. If so, the ID is tested against previous written IDs (if there are previous writes, all IDs must be equal) and stored.

If the packet is a one word write to the IDCODE register, this word is the device ID.

Parameters:

type2Packet The packet.

Exceptions:

.
