还有一种叫做VLV（Very-low-voltage test)的测试，将电源电压设置为 CMOS晶体管阈值电压 （Vt）的2~2.5倍来测试。 随着IC Vdd的降低， VLV测试 和Vmin测试的差异在逐渐消失，先进工艺中不需要做专门区分。 一般Vmin筛选包括以下步骤： 1.

Energy efficiency of electronic devices has risen to become the top concern in recent years. Lowering minimum operating voltage (Vmin) without sacrificing perfo

We have presented the investigation on the minimum operating voltage (Vmin) versus key process parameters using advanced sub-10nm CMOS process, showing that the significant contributors to Vmin are the sum of Vth for n-/p-FETs and random variability in respect of INV and FF, respectively.

2022年10月24日 · This process and its benefits for Vmin optimization are fully supported by the Synopsys Silicon Lifecycle Management solution. It includes Synopsys SLM Path Margin Monitor IP to measure timing margins for real paths in-test or in-field.

CPU pessimistic voltage margins set by hardware designers to address voltage-noise, aging and static variations, limit the power efficiency of computing systems. These margins are necessary to avoid voltage emergencies that lead to silent data corruption and application/system crashes which are not acceptable in most situations. However, the …

In this work, we propose a fast analytical model, which takes into account the supply-voltage, temperature, process-variations, and array-design variables to characterize the critical read path and the small signal differential sensing and then evaluates the read-access failure probability and the corresponding VMIN and yield.

As a result, it has become a widespread practice during post-silicon testing to explore lower operating voltages on a silicon testbench, also known as Vmin analysis, and find the lowest operating voltage that a design can continue to operate properly. The result will be used to influence the decision if new libraries are characterized.

Vmin的测试是通过实验测试来完成的，测试人员会逐步减少电源电压，并监测器件的性能指标，直到器件无法正常工作为止。 在这个过程中，测试人员需要密切关注器件的电流、电压、功率等参数，以及器件的温度和噪声等指标。 Vmin的实际意义在于，当电源电压低于Vmin时，半导体器件的工作效率会受到影响，甚至无法正常工作。 因此，Vmin可以用于筛选器件，即在Vmin以下的器件可以被认为是不合格的。 此外，Vmin还可以用于评估器件的性能，即在Vmin下工作的器件性 …

Basically as a Vmin shipper I might want to try to find reasons for the rumors that still allow my view of Vmin as a couple to remain intact. This is a danger I have spoken about myself before …

2025年2月20日 · The transition to retention mode involves several hardware and software interactions, including voltage scaling, clock gating, and state retention. At Vmin, the margin for error is minimal, and any misstep in the transition process can lead to data corruption, state loss, or even system failure.
