Troubleshooting the Logic Analyzer

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 is 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.

❏ Verify that the inverse assembler has been synchronized by placing an

opcode at the top of the display (not at the input cursor) and pressing the

Invasm key.

Because the inverse assembler works from the first line of the trace

display, if you jump to the middle of a trace and select Invasm, prior trace

states are not disassembled correctly. If you move to several random

places in the trace list and select Invasm each time, the trace disassembly

is only guaranteed to be correct from the top of the display forward for

each selection.
