Inverse Assembler Problems; No Inverse Assembly Or Incorrect Inverse Assembly - HP E2416B User Manual

Inverse Assembler Problems

This section lists problems that you might encounter while using the
inverse assembler.
When you obtain incorrect inverse assembly results, it may be unclear
whether the problem is in the analysis probe or in your target system.
If you follow the suggestions in this section to ensure that you are
using the analysis probe and inverse assembler correctly, you can
proceed with confidence in debugging your target system.

No inverse assembly or incorrect inverse assembly

This problem may be due to incorrect alignment, modified configuration files,
incorrect connections, or a hardware problem in the target system. A locked
status line can cause incorrect or incomplete inverse assembly.
Ensure that each logic analyzer pod is connected to the correct analysis
probe connector.
There is not always a one-to-one correspondence between analyzer pod
numbers and analysis probe cable numbers. Microprocessor interfaces must
supply address (ADDR), data (DATA), and status (STAT) information to the
analyzer in a predefined order. The cable connections for each analysis
probe are often altered to support that need. Thus, one analysis probe might
require that you connect cable 2 to analyzer pod 2, while another will require
you to connect cable 5 to analyzer pod 2. See Chapter 2 for connection
information.
Check the activity indicators for status lines locked in a high or low
state.
Verify that the STAT, DATA, and ADDR format labels have not been
modified from their default values.
These labels must remain as they are configured by the configuration file. Do
not change the names of these labels or the bit assignments within the labels.
Some analysis probes also require other data labels. See Chapter 3 for more
information.
