Appendix A Self-Checking Program (SCP)
This section gives the procedure for using the self-checking program for the E1 and E20 in fault analysis.
A.1 Flow of Self-Checking
Install the emulator software.
Install the SCP and USB driver for the E1 and E20 on the
host computer (this step is only required once).
↓
Connect the user interface cable. Connect one end of the user-system interface connector to
the user-side connector and the other end to the self-
checking connector on the emulator (see Figure A.1).
Do not connect the USB interface connector yet.
↓
Connect the USB interface cable*. Connect the host computer a
nd the emulator via the USB
interface cable and turn on the power for the emulator.
E1: The supply of power starts when the USB interface
connector is connected.
E20: The supply of power starts when the power switch is
turned on after the USB interface cable has been
connected.
↓
Initiate the SCP for the E1 and E20.
Initiate the SCP.
↓
Execute the TEST1 and TEST2 programs.
Execute the TEST1 and TEST2 programs.
↓
Disconnect the user interface cable.
Remove the cable from the self-checking connector.
↓
Execute the TEST3 program.
Execute the TEST3 program.
↓
View the results of self-checking.
If the results were normal, “PASS” will be displayed. If
checking indicated a failure, “FAIL” will be displayed.
In the case of “FAIL”, a further error message is also given.
For the messages and their meanings, see Table A.1.
Note: Fault analysis of the hardware by using the self-checking program only works correctly when a single
emulator is connected to the host computer. When two or more
emulators are connected, correct
operation is not guaranteed.
