Trace buffer technology allows tracking the values of a few number of state elements inside a chip within a desired time window, which is used to analyze logic errors during post-silicon validation. Due to limitation in the bandwidth of trace buffers, only few state elements can be selected for tracing. In this work we first propose two improvements to existing “signal selection” algorithms to further...
Due to the growth of both design complexity and the number of gates per pin, functional debugging has emerged as a critical step in the development of a system-on-chip (SOC). Traditional approaches, such as system emulation and simulation, are becoming increasingly inadequate to address the system debugging needs. Design simulation is two to ten orders of magnitude slower than emulation and, thus,...
