Kibra DDR Protocol Analyzer User Manual
based on the nanosecond values that the timing values would have been for the nominal
DIMM Speed, adjusted to the clocks as calculated from the Speed parameter.
Speed
The data transfer rate. These are used to determine the appropriate JEDEC violation
values. Select from the drop‐down speeds of DDR3‐800 to DDR3‐2133. Or use the Refresh
icon to have the Kibra 380 Protocol Analyzer or Kibra 480 DDR4 Protocol Analyzer
hardware automatically detect the DIMM Speed. This works when memory is actively
being accessed.
Case Temperature
The Case Temperature of the DIMM in Celsius.
DRAM Density
The memory density of the SDRAMs. Select from the drop‐down options from 512MB to
8GB.
Data Width
Select from three data width options from the dropdown menu: x4, x8, x16.
Row Address Count
Select from the drop‐down options from 12 to 16.
Page Size
The Page Size is determined by the OS. Select from 1KB or 2KB.
Burst Length
Two Burst Lengths can be selected from the drop‐down menu, BC4 (Burst Chop 4) or BL8
(Burst Length 8). Burst Length OTF (On‐The‐Fly) is not currently supported. For systems
which use OTF, select either one. This will be used to calculate data bandwidth, since
Kibra does not directly capture the data.
CL (nCK)
Select a CAS Latency from a range of 5 to 18.
CWL (nCK)
Select a CAS Write Latency from a range of 5 to 16.
Timing Mode
This determines whether the control signals require a multiple of clocks to perform at the
data rate selected in the Speed drop‐down field. Select from a multiplier value of 1T, 2T
and 3T.
AL
Additive Latency is the CAS Latency minus one or minus two. Select zero for no AL, CL‐1
or CL‐2.
