Scenario Events Teledyne LeCroy
The following sections provide some additional details about three of the above events.
DWORD Matcher
DWORD Matcher is a DWORD pattern matcher that presents match and mask fields and a
K‐Code Mask field. K‐Codes are control characters that are always used in the first byte of
a four‐byte primitive. Of the K‐Code masks listed in the menu, D‐D‐D‐D is used for data
bytes, and K‐D‐D‐D is used for all primitives.
When you create a DWORD match, keep the following in mind:
 The pattern can be inside or outside of frames (it does not matter if the pattern
is inside a frame or not).
 Because the pattern can be inside or outside of frames, there is no offset.
 You can make user‐defined primitives. (This is the reason this feature was cre‐
ated.)
 You can use any K/D pattern.
SAS Data Pattern
When you create a SAS data pattern, keep the following in mind:
 The pattern must be defined inside a frame that starts with a SOF or SOAF.
 The pattern must be data only (no K‐codes/primitives).
 The pattern must be defined at a specific offset in the frame.
 The pattern and mask must be specified in the same format as specified in the
SAS standard: 
0x12345678 (hex)
where “1” is the first digit on the cable and is the MSB as given in the SAS Stan‐
dard.
For example, for an SMP Request:
Pattern: 0x40000000
Mask: 0xFF000000
Offset: 0
SOF Type: SOF
SATA Data Pattern
When you create a SATA data pattern, keep the following in mind:
 The pattern must be defined inside a frame that starts with a SATA_SOF.
 The pattern must be data only (no K‐codes/primitives).
 The pattern must be defined at a specific offset in the frame.
 The pattern and mask must be specified in the same format as specified in the
SATA Standard.
