Key features and benefits:
• Decodes DDR2, DDR3, or DDR4
acquired traces on Agilent logic
analyzer or off-line
• Displays commands, protocol
transaction type, physical/row/
column/bank addresses, and data
in the listing viewer
• Data is displayed at any level of
detail from protocol to binary
• Anticipates key system attribute
inputs from default probing
configurations and/or DDR Setup
Assistant tool
• Allows user input to customize
system attributes
Description
Accelerate your time to insight using the B4621B bus decoder for DDR2, DDR3,
or DDR4 debug and validation. The B4621B provides complete protocol decode
of memory transactions using an Agilent logic analyzer as the analysis execu-
tion engine. (Select your logic analyzer module depending on your system data
rate.)
The B4621B protocol-decode software translates acquired signals into easily
understood, colorized, bus transactions showing associated data bursts for
double-edge data-rate captures up to 2.5 Gb/s.
Valid Read and Write commands are decoded to include Row and Column
Addresses and the complete data burst associated with the command. The
B4621B bus decode software anticipates key system attribute inputs (Burst
length, CAS Latency and CAS Write Latency, Chip Selects) from default DDR2,
DDR3, or DDR4 probing configurations and/or DDR Setup Assistant tool to
accelerate decode of DDR2, DDR3, or DDR4 bus signals.
