Snoop
0 indicates that hardware enforced cache
coherency is expected.
1 indicates that hardware enforced cache
coherency is not expected.
Ordering
0:1
0
Bit 5 of byte 2 of TLP header:
0 indicates PCI Strongly Ordered Model.
1 indicates PCI-X Relaxed Ordering
Model.
Length
0:1023
1
Length of data payload in DWORDs.
If not specified, this field is 1 for all read
requests and calculated according to the
actual payload for write requests.
For a length of 1024, set Length to 0
(because 0 means 1024).
Tag
0:255
LAST_CFG_TAG
LAST_IO_TAG
LAST_MEM_TAG
0
Byte 6 of the TLP Header for Memory, IO,
and Configuration TLP packets.
Byte 10 for Completion TLP packets.
When Tags are generated automatically
(see the TagGeneration parameter, Page
38), this parameter has no effect for
Memory, IO, and Configuration TLP
packets.
The LAST_CFG_TAG,
LAST_IO_TAG, and
LAST_MEM_TAG modifiers are only valid
for the Summit Z2-16 and Summit Z3-16
Trainers and are only applicable to
Completion TLPs.
When a LAST_CFG_TAG,
LAST_IO_TAG, or
LAST_MEM_TAG modifier is used for a
completion TLP, the Tag field value is set
to the value of the Tag in the latest-
received Configuration, IO, or Memory
request, respectively, as seen by the Z2-
16 and Summit Z3-16 trainers.
RequesterID
(XX:XX:X) or direct
value
0
Bytes 4-5 of the TLP Header for Memory,
IO, and Configuration TLP packets.
Bytes 8-9 for Completion TLP packets.
This parameter can be set in the following
format: (BusNumber :
DeviceNumber : FunctionNumber)
ECRC
0x00000000:
0xFFFFFFFF
Calculate
d
automati
cally
When not specified, the PETracer™
software automatically calculates the
ECRC. (TD field has to be specified.)
LCRC
0x00000000:
0xFFFFFFFF
Calculate
d
automati
cally
When not specified, the PETracer
software automatically calculates the
LCRC.
When LCRC is generated automatically
by the PETrainer™ hardware (see the
AutoLCRC parameter, Page 38), this
parameter has no effect.
