“…The MER method also makes the transient simulation more efficient by providing a shorter bit pattern, thereby generating the eye diagram with the worst contour [44]. The transient simulation requires test bit patterns as an input to generate the waveforms.…”

An eye diagram, a critical metric in signal integrity analysis for high-speed interconnects such as packages, interposer, and printed circuit boards (PCBs), is generated by superposition of the received waveform. Obtaining an eye diagram is time-consuming, thus signal integrity analysis is inefficient. This article reviews that have been proposed to overcome this limitation. The statistical eye diagram provides a probability distribution depending on a sampling time and voltage, therefore it can be expanded to other metrics, such as the bit-error rate and shmoo plot. This article introduces previous research on statistical eye diagrams applied to complementary metal-oxide-semiconductors (CMOSs), noise, and high-speed systems. The methods applied to CMOSs include asymmetry between the P/NMOS transistors and the nonlinearity of the CMOS. The methods applied to noise include signal and power noise. The methods applied to high-speed systems include equalizers, signaling, encoding, linear feedback shift register, and error correction code.INDEX TERMS Complementary metal-oxide-semiconductor (CMOS), crosstalk, double edge response (DER), error correction code (ECC), encoding, equalizer, eye diagram, multiple edge response (MER), pulse amplitude modulation (PAM), package, single bit response (SBR), signal integrity (SI), statistical eye diagram.
