Question

Which of the following does not have the ability to get hundred individual signal cables into the probe in the emulation technique?

(a) OnCE

(b) BDM

(c) ICE

(d) JTAG

The question was asked during an internship interview.

The above asked question is from Emulation Techniques in chapter Emulation and Debugging Techniques of Embedded Systems

Answer 1

Right answer is (c) ICE

The best I can explain: The in-circuit emulation does not have the ability to get a hundred individual signal cables into the probe. This problem comes under the physical limitation of the probe, that is as the density of the processor increases the available sockets which provide good electrical contacts is becoming harder which causes a restriction to the probe.
