Test scripts can customize ReadyLink Emulation Mode to include error scenarios, such as:
Header LBADs
Invalid link commands
8B10B / CRC Error
Running Disparity Error
Corrupt Link Commands
Corrupt Flow Control (Wrong L_CRD_x, Wrong L_GOOD_n, Drop L_Good_n)
Corrupt Header Packet acknowledgement (Send LBAD, LRTY)
Corrupt Packet Framing (SHP, SDP, END)
At the packet level, you can send customized data payloads anywhere within the stream to insert
logic errors, perform corner-case, or do stress testing. Commands, such as the Set
ErrWrongLCRD command, allow link-layer error injection anywhere within the script.
1.1 Declaration Conventions
1.1.1 Parentheses
In declarations and descriptions of Generation Script Language instructions,
the format
"(" ")"
specifies a list of keywords that have the same value and can replace
each other. The declaration
( Packet | Struct ) Template_Name …
specifies that you can use the "Packet", "Packet", or "Struct" keyword for template name
declarations.
1.1.2 Brackets
In declarations and descriptions of Generation Script Language instructions,
the format "
[ " " ] " specifies optional parts of declarations or instruction parameters. The declaration
( Packet | Struct ) Template_Name [ Ancestor_1, Ancestor_ 2, … ] [ (Attribute list) ]
specifies that the listed ancestors and attribute lists are optional for template name declarations.
