Chapter 12: Emulator Error Messages
Event "expr" cannot be combined with expression definition (Error 1256)
Event "expr" cannot be combined with expression definition (Error 1256)
Cause: The terminal interface tgout (trigger output) command of the deep analyzer
may use an arbitrary expression as an event to drive the trig1 and/or trig2 signals to
the emulator. This expression can be set up in two ways. One way uses two tgout
commands; the first command defines the signals and type of events, and the
second command defines the expression. This is most useful when defining
complicated expressions. The other way uses one tgout command which defines
the expression as the event. This error message indicates that you have tried to
combine the two methods.
Action: Reenter your tgout command using the correct format for the command.
Refer to the tgout command description in the chapter titled "Interfaces of the Deep
Analyzer" for correct formats for the tgout command.
Failed to disable step mode (Error 684)
Cause: System failure. Run performance verification (pv command).
FATAL SYSTEM SOFTWARE ERROR (Error 204)
FATAL SYSTEM SOFTWARE ERROR (Error 205)
FATAL SYSTEM SOFTWARE ERROR (Error 208)
Cause: The system has encountered an error from which it cannot recover.
Action: Write down the sequence of commands that caused the error. Cycle power
on the emulator and reenter the commands. If the error repeats, call your local HP
Sales Office for assistance.
File could not be opened
Cause: The file cannot be opened or created for writing.
Action: Check to make sure that the parent directory for the file has correct
permissions set.
