analyzer count in either time or the occurrences of some state.
When counts are specified, only 512 states can be stored.
The analyzer's sequencer allows you to trigger after a sequence of
states are captured. Up to 7 sequence terms (the last of which is
the trigger term), each with an option occurrence count, are
available. A sequence restart term is also available.
Windowing refers to the ability to capture activity between one
state and another. Up to 4 sequence terms are available when
windowing is in effect.
When multiple HP 64700-Series emulators are connected via the
Coordinated Measurement Bus (CMB), you can use the analyzer to
trigger the analyzers of other emulators. You can also use the
analyzer to trigger instruments connected to the BNC port.
Conversely, analyzer measurements may be started by other
emulators and instruments.
The Software Performance Measurement Tool (SPMT), which is
part of the Softkey Interface, allows you to make measurements on
the performance of your programs. You can measure activity in
address ranges, or you can measure the average time it takes during
and between execution of a program module.
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.
The timing analysis information is available through the Softkey
Interface timing analyzer software residing on a HP-UX host. The
software allows you to control the external timing analyzer, acquire
timing measurements, analyze the trace measurements for specific
occurrences, display the information in graphic or tabular form,
and save the trace information for subsequent comparisons.
