请帮忙看看以下几个名称的具体含义：minWC, avgTW

谢谢。
我已经大概知道maxTW，avgTW的含义。
"avgTW", average effective voltage (Vdd-Vss) over the timing window, “minTW”, minimum effective voltage over the timing window, “maxTW”, maximum effective voltage over the timing window.
只是minWC还是没有概念。
下面给个上下文语境，希望各位帮忙参详一下。
it reports the worst percentage DvD values for all arcs for the
selected base parameter (default avgTW). You can select a different base value,
since the worst MinTW, maxTW, or minWC values from one arc may not be the
worst among multiple arcs for the same instance.
