Understanding Effective Instance Voltage (EIV) for IR Drop-Aware Timing

Effective Instance Voltage (EIV) is a critical metric in rail analysis, helping designers evaluate the worst-case voltage between power and ground pins during specific simulation windows. In this video, learn what EIV is, how it’s calculated, and why it matters for IR drop-aware timing analysis and chip reliability. EIV is computed by processing voltage waveforms and identifying the worst rail-to-rail voltage during evaluation windows such as switching, timing, both, or elapse. Tools like Voltus use these windows to determine accurate EIV values for IR drop and ground bounce scenarios. We also explain how EIV reports are generated and interpreted, including fields like Win EIV, PWR win IV, and GND win IV.
