Board Path Entries The first series of entries in this file describe the scan paths on the board and the devices on those
paths. Each of these entries begins with the keyword Board_Path followed by the path number. The entries end with the
keyword End_Board_Path. Between the beginning and ending tags the devices on the path are defined. A device entry
begins with the keyword Device and is followed by the devices reference number, the device name, the devices reference
designator, a boolean indicating whether the device is required, and finally the devices removal order.
• Device number—integer
• Device name—string
• Reference designator—string
• Required flag—TRUE | FALSE
• Removal order—integer
NOTE The removal order determines which non-required devices are missing if less than the maximum number
of devices are encountered. The lower the removal order the more likely the device is missing.
Link Connection Entries Each link connection to this board needs to have an entry in this file. Link entries contain
primary and secondary link connection information. A link entry is specified as follows.
Each entry begins with the keyword Link_Type followed by the link type number and ends with the keyword,
End_Link_Type. Between the begin and end are entries for Primary and Secondary link connections. A primary link
connection is the originating connection. The secondary entries are destinations for the link.
A primary link connection begins with the keyword Primary and ends with the keyword End_Primary. Between the begin
and end tags the possible connections are listed as specified below:
• ID—Cable number of device selector number
• lookup—Number added to look up the correct entry
• loopback—Flag that indicates whether the connection is a loopback connection
• type—String that indicates the type of cable being processed
• part number—Part number of the cable as a string
• name—String representing the name of the link cable
Secondary link connections begin with the keyword Secondary and end with the keyword End_Secondary. Connections
on a secondary link follow the same format as those of a primary link but use two less fields.
Link connections begin with the keyword Connection followed by the following fields.
• ID—Cable number of device selector number
• lookup—Number added to look up the correct entry
• loopback—Flag that indicates whether the connection is a loopback connection
• type—String that indicates the type of cable being processed
End of File This file must end with the keyword End_Of_File.
