ABSTRACT
Microprocessors are becoming increasingly complex
and difficult to debug. Researchers are constantly looking
for new methods to increase the observability and control-
lability of microprocessors. This paper introduces a new
method to improve the observability of modern micropro-
cessors and thus simplifying the task of debugging them.
The method revolves around an observation circuit that
provides access to important internal signals without inter-
rupting the microprocessor execution. The output of the
observation circuit is ported to the output of the micropro-
cessor in order to easily detect various physical faults and
design errors. Experimental results show that physical
faults and design errors are detected faster using our
method. Moreover, several errors are detected by the
observation circuit without being detected by the micropro-
cessor outputs.
Keywords: Post-silicon verification, observability
improvements, microprocessors, design for debug.
