Chapter 5: Using the Emulation-Bus Analyzer
Making Complex Trace Measurements
Values, symbols, and operators may be used together in analysis specification
expressions. For example, if the local symbol exists, the following is a valid
expression:
module.c:symb+0b67dh&0fff00h
However, you cannot add two symbols unless one of them is an EQU type symbol.
Emulation-Bus Analyzer Trace Signals
The emulation-bus analyzer has 80 channels available for capturing information: 64
of those channels are used for the instruction bus and data bus, and the remaining
16 channels monitor other processor signals or synthesized signals, and are
collectively called the status lines. You can use status values as trigger or storage
qualifiers. For example, you may want to capture processor reads to a certain
address, but not processor writes. You can use a status value to qualify only
processor read cycles to the memory location.
A number of status values have already been defined for you. They are collectively
known as the status equates and cover most common processor operations. Status
equates appear on softkeys at the appropriate time so you can include the status you
want in your command line.
