Example Simultaneous Handoff Mode Transfer
E84 Handoff Modes
The SEMI ® E84 Specification defines three types of handoff modes, Single, Simultaneous, and
Continuous. The E84 Emulator supports all three handoff modes. This section briefly describes each
mode, and explains the associated testing capabilities of the E84 Emulator .
Single Handoff Mode
Single Handoff Mode is used to transfer a single carrier to or from a Load Port. The AMHS equipment
defines the target Load Port at the beginning of the handoff sequence, using one of the Load Port select
signals (CS_0, CS_1). Only one of the two signals is activated during the handoff sequence.
The figure at right shows E84 interface signals recorded
during a typical Single Handoff Mode transfer. The
timing diagram shows the CS_0 signal turning ON to
indicate a Single Handoff Mode transfer.
The E84 Emulator Application provides 17 active
mode tests (Emulator acts as the active equipment) that
can be run using Single Handoff Mode. These tests are
selectable from the
Active Mode Test Setup Screen ,
which can be reached from the Main Menu using the
Automatic Active Mode Testing button. To configure a
Single Handoff Mode test, simply select either the CS_0
or CS_1 button from the
LOAD PORT NUMBER
field on the
Active Mode Test Setup Screen .
The E84 Emulator Application provides 15 passive mode tests (Emulator acts as the passive equipment)
that can be run using Single Handoff Mode. These tests are selectable from the Passive Mode Test Setup
Screen , which can be reached from the Main Menu using the Automatic Passive Mode Testing button.
The active equipment sets the Load Port select signals. Therefor, in passive mode testing there are no
Load Port select options. The Emulator simply provides the proper transfer handshaking, while monitoring
and verifying the Load Port select signals detected at the beginning of the transfer.
Simultaneous Handoff Mode
Simultaneous Handoff Mode is used to transfer two carriers concurrently to or from two separate Load
Ports. The AMHS equipment indicates a Simultaneous Handoff by setting
both Load Port select signals
(CS_0 and CS_1). Both signals remain activated during the handoff sequence.
The figure at right shows E84 interface signals recorded
during a typical Simultaneous Handoff Mode transfer.
The timing diagram shows the CS_0 and CS_1 signals
turning ON, indicating a Simultaneous Handoff Mode
transfer.
The 17 active mode tests provided by the E84
Emulator Application can be run in Simultaneous
Handoff Mode as well as Single Handoff Mode. The
only difference between Single and Simultaneous
Handoff Modes is the use of the two Load Port select
signals. This allows the
E84 Emulator Application to
use the same pre-defined tests to verify both Single and
Simultaneous Handoff sequences. To configure a
Simultaneous Handoff Mode test, simply select the
Simultaneous button from the
LOAD PORT NUMBER
field on the Active Mode Test Setup Screen .
