Chapter 5: Verification Script Engine Input Context

Members

All verification scripts have input contexts –special structures whose members are filled by the

application and can be used inside of the scripts. (For more details about input contexts, refer

to the CATC Script Language(CSL) Manual.. The verification script input contexts have two

sets of members:

o Trace event-independent set of members

o Trace event-dependent set of members

5.1 Trace Event-independent Set of Members

This set of members is defined and can be used for any event passed to script:

in.Level Logical level of the trace event: 0 = Link, 1 = Transport, 2 =

Application.

in.Index Index of the event in the trace file: frame number for frames,

sequence number for sequences.

in.Time Time of the event: type = list, having format

2 sec 125 ns -> [2 , 125]. (See VSE time object

for details.)

in.Duration Duration: time that packet contains.

in.Channel Channel where the event occured: may be _CHANNEL_1 (1) or

_CHANNEL_2 (2), indicating which direction of the SAS/SATA link

the event occurred)

in.TraceEvent Type of trace event: application predefined constants are used.

See the list of possible events

below.

in.Notification Type of notification: application predefined constants are used.

Currently, no notifications are defined.

in.LinkSpeed Speed of the trace event: may be _LINK_SPEED_1_5 (1.5 Gbps) or

_LINK_SPEED_3_0 (3Gbps) or _LINK_SPEED_6_0 (6Gbps)

*Gbps – Giga Bits per second

in.ProtocolErrorMask A bitmask pattern contains detected errors on the specified event:

Each bit on this mask demonstrates a possible error. To know about

error bit position look at See SendProtocolError

for details.

In.DWORDS All DWORDs of current packet: type = list of list, having format

DWORD: SOF, count : 1, Error: no error -> [“SOF”, 1, 0]

DWORD: 50E80050, count : 1, Error: Has an error -> [“50E80050”, 1,

… …..

[[“SOF”, 1, 0], [“50E80050”, 1, 1], …]

Note: For SATA/STP frame, if trace has been captured with M6-4, M6-2 or M6-1, “Host” and

“Device” are coming sequentially one after other: [ [Host], [Device], [Host], [Device], ….]

1 2 ... 11 12 13 14 15 16 17 18 19 20 21 ... 96 97
