Analyzer Features
This chapter lists basic features of the HP 64700 Series analyzer. The
chapters which follow show you how to use these features.
Simple Measurements
The default condition of the analyzer allows you to perform a simple
measurement by entering a single "analysis begin" command. You can
enter additional trace commands to qualify when execution should be
traced and which bus cycle states should be stored.
Trace Storage,
The analyzer can store up to 1024 states in trace memory. These states
can be normal storage states or prestore states (states which precede
Prestore, and Count
normal storage states). A count may be associated with normal storage
states; you can specify that the analyzer count in either time or the
occurrences of some state. When counts are specified, only 512 states
can be stored.
Sequencer
You can use the analyzer to search for a particular sequence of states.
The sequencer, which makes this possible, has several levels. Each
level of the sequencer searches for a "find" or "trigger" state. When the
find/trigger state is captured, the analyzer goes on searching at the
following sequence level. If branches are turned on, a "branch" state is
also searched for in each sequence level. If the branch state is found
before the find/trigger state, the analyzer can jump to any sequence
level where it continues searching for states.
External Analysis
Your HP 64700 Series emulator may optionally contain an external
analyzer. The external analyzer provides 16 external trace signals and
two external clock inputs. You can use the external analyzer as an
extension to the emulation analyzer, as an independent state analyzer,
or as an independent timing analyzer.
