58 Function Block and Operation Theory
Event
PM O
Pattern Match Event
– A pulse signal out-
put to indicate the event of pattern match
of user-defined data lines.
COS O
Change Detection Event
– A pulse signal
output to indicate the change detection of
any user-defined data lines.
Handshake
DI-REQ I
Digital Input Reques
– In handshaking
mode for DI pattern acquisition, DI-REQ
carries handshaking control information
from DUT to PCIe-7350.
DI-ACK O
Digital Input Acknowledge – In hand-
shaking mode for DI pattern acquisition,
DI-ACK carries handshaking status infor-
mation from PCIe-7350 to DUT.
DI-TRIG I
Digital Input Trigger
– In handshaking
mode for DI pattern acquisition, DI-TRIG
can be used to start the operation.
DO-REQ O
Digital Output Request
– In handshaking
mode for DO pattern generation, DO-REQ
carries handshaking control information
from PCIe-7350 to DUT.
DO-ACK I
Digital Output Acknowledge
– In hand-
shaking mode for DO pattern generation,
DO-ACK carries handshaking status infor-
mation from DUT to PCIe-7350.
DO-TRIG I
Digital Output Trigger – In handshaking
mode for DO pattern generation, DO-TRIG
can be used to start the operation.
