Teledyne LeCroy Sierra Trainer Generation Language
306 Sierra M124 SAS/SATA Protocol Analyzer User Manual
 Raw 10 bits codes. This definition might cause running disparity errors.
Example:
Primitive "CHAIN (TWO)" = 305 2D4 1E4 362
 Mixed bytes and 10b codes. This definition might cause running disparity errors.
Example:
Primitive "CHAIN (TWO)" = 305 2D4 1E4 362 ["CHAIN (ONE)"]
Packets/ Frames
Using the “Frame” or “Packet” keyword, you can define a frame of traffic to use in the
generation stream. Declarations of prolog and epilog may be mixed with field
declarations.
Frame "name" : "parent name"
{
Field Definition 0: "Field Name : Field Length = Default Value"
…
Field Definition n: "Field Name : Field Length = Default Value"
Primitive Definition 0: "Primitive name, offset, count"
…
Primitive Definition m: "Primitive name, offset, count"
Prolog = "primitive name"
Epilog = "primitive name"
}
Field Definition
 Field length is in bits. '*' means that the length is variable and is set based on the
assigned value.
 Field starting offset is calculated from frame start based on the length of the pre‐
vious fields.
Examples:
Field32 : 32 = 0xAABBFFEE
FrameType : 8 = 12
HashedDest : 24 = HEX_DATA
Reserved1 : 8 = 0xDA
Field16 : 16 = 0xAAAA
Reserved2 : 8 = 0xAD
CRC : 32
Data field Definition
• Data = { pattern }: Pattern is assigned to Data.
• Data = count, value: A pattern of “count” times “value” is assigned to Data.
• Data = count, start value, step: A pattern of values starting with “start value” with steps of “step”
and a length of “count” is assigned to Data.
