through 15 and the K clock). You can specify a threshold voltage for each of
these groups.
The default threshold voltages are specified as TTL which translates to 1.40
volts.
Voltages may be in the range from -6.40 volts to 6.35 volts (with a 0.05V
resolution). You may also specify CMOS (which translates to 2.5 volts), or
ECL (which translates to -1.3 volts).
To specify the external analyzer mode
1
Choose "yes" for the "Should emulation control the external bits"
configuration option.
2
Choose "Emulation", "State", or "Timing" for the "External analyzer
mode" configuration option.
The default configuration selects the "emulation" external analyzer mode. In
this mode, you have 16 external trace signals on which data is captured
synchronously with the emulation clock.
The external analyzer may also operate as an independent state analyzer, or
it may operate as an independent timing analyzer if a host computer interface
program is used.
Choose "emulation" to select the emulation mode. In this mode, the external
analyzer becomes an extension of the emulation analyzer. In other words,
they operate as one analyzer. The external bits are clocked with the
emulation clock. External labels may be used in trace commands to qualify
trigger, storage, prestore, or count states. External labels may be viewed in
the trace display.
Choose "state" to select the independent state mode of the external analyzer.
The external bits are not available for use from the emulation interface. You
can, however, use pod commands to control the external state analyzer in its
independent mode.
Choose "timing" to select the timing mode of the external analyzer. The
external bits are not available for use from the emulation interface. Because
the pod commands for the timing analyzer dump information in binary
format, you will need to use Timing Analyzer Interface, or other interface
program, to capture the timing analyzer data.
