true, the IICE will trigger, indicating that the instruction register is be-
ing written with a new value after reset.SUMMARY
In this chapter we explored a new technique to debug designs using ac-
tual hardware implementations. The concepts behind instrumenting a de-
sign were introduced and techniques for instrumenting a design were
shown. Next we discussed techniques for setting trigger conditions to find
specific design states during debug. Finally we discussed how to specify
complex triggers to precisely define trigger behavior.412 Chapter Eighteen
