68302 Emulation and Analysis
The HP 64746 68302 emulator replaces the microprocessor in your embedded
microprocessor system, also called the target system, so that you can control
execution and view or modify processor and target system resources.
The emulator requires an emulation analyzer that captures 64 channels of emulation
processor bus cycle information synchronously with the processor's clock signal.
The HP 64703 Emulation Bus Analyzer meets this requirement, and it has an
external analyzer that captures up to 16 channels of external data.
You can use the HP 64704 or HP 64794 Emulation Bus Analyzers which have 80
channels; however, these analyzers do not have external analysis channels.
You can also use the HP 64706 Emulation Bus Analyzer which has 48 channels.
Because this analyzer has fewer channels, you cannot capture all the
microprocessor bus cycle information that you can with the other analyzers.

Plug into 68302 target systems.
Download programs into emulation memory or target system RAM.
Display or modify the contents of processor registers and memory resources.
Run programs, set up software breakpoints, step through programs, and reset
the emulation processor.
Trigger the analyzer when a particular bus cycle state is captured. States are
stored relative to the trigger state.
Qualify which states get stored in the trace.
Prestore certain states that occur before each normal store state.
Trigger the analyzer after a sequence of up to 8 events have occurred.
Capture data on signals of interest in the target system with the external
analyzer.
Cause emulator execution to break when the analyzer finds its trigger condition.
