Inverse Assembler Problems; No Inverse Assembly Or Incorrect Inverse Assembly - HP E2465A PowerPC 604 PGA 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 preprocessor or in your target system. If
you follow the suggestions in this section to ensure that you are using
the preprocessor 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 synchronization, modified
configuration, incorrect connections, or a hardware problem in the target
system. A locked status line can cause incorrect or incomplete inverse
assembly.
D Ensure that each logic analyzer pod is connected to the correct
preprocessor connector.
There is not always a one-to-one correspondence between analyzer pod
numbers and preprocessor cable numbers. Preprocessors must supply
address (ADDR), data (DATA), and status (STAT) information to the
analyzer in a predefined order. The cable connections for each preprocessor
are often altered to support that need. Thus, one preprocessor 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 1 for connection information.
D Check the activity indicators for status lines locked in a high or low
state.
D Verify that the STAT, DATA, DATA_B, 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 preprocessors also require other data labels. See Chapter 2 for more
information.
