Prestore, and Count
This manual describes the HP 64700-Series analyzer. Each HP
64700-Series emulator contains an emulation analyzer. Your
emulator may optionally contain an external analyzer. (If your
emulator contains an external analyzer, an "L" suffix appears on the
serial number tag, for example, "64742AL SN ...".)
The emulation analyzer captures emulator bus cycle information
synchronously with the processor's clock signal. A trace is a
collection of these captured states. The trigger state specifies when
the trace measurement is taken. The external analyzer captures
activity on signals external to the emulator, typically other target
system signals.
The analyzer commands are the same in every emulator;
consequently, this manual is shipped with every HP 64700-Series
emulator ordered with the Softkey Interface.
This chapter lists basic features of the HP 64700-Series analyzer.
The chapters which follow show you how to use these features.
The default condition of the analyzer allows you to perform a
simple measurement by entering a simple "trace" command. You
can add qualifiers to the trace command to specify when execution
should be traced and which bus cycle states should be stored.
The analyzer can store up to 1024 states in trace memory. These
states can be normal storage states or prestore states (states which
precede normal storage states). A count qualifier may be
associated with normal storage states; you can specify that the
