Verifying Operation Of The Emulator In Your
Target System
When connecting an emulator into a new target system, the step-by-step approach
described in the remainder of this chapter will help you get your system running
most quickly. This is a logical procedure that starts out with the most simple
requirements and moves toward compete functionality, allowing for verification of
installation at each step of the way. This not only helps debug problems if they
arise, but builds confidence that the emulator is functioning correctly in your target
system.
To begin, run the performance verification procedure described in Chapter 19,
"Installation and Service".
Some additional equipment may be required to make measurements of MC68040
signals. It will help to have an oscilloscope and high speed timing analyzer to use
during these procedures. A 250-MHz timing analyzer may be fast enough, but
faster is better. The oscilloscope should have a single-shot bandwidth greater than
500 MHz. You may also need to cross trigger these instruments from the emulator.
If there are no trigger inputs to the timing analyzer, you can probably use a timing
channel. The BNC trigger output of the 64700 emulation card cage provides a
rising edge TTL signal.
When making measurements, remember that signals need to be probed at the right
place for the measurement being made. The emulator specifications are referenced
to the target socket connector on the probe. This is where measurements should be
made to verify compliance with the specifications. When probing setup and hold
times to circuits in the target system, make the appropriate measurements at the
circuits. This will keep connection accessories from impacting the true
measurements. Always use ground leads to get the most accurate measurements
possible.
