本页汇总 oaPiElmore 当前在 oapy 中可用的 Python 接口。

详细说明

The oaPiElmore class represents a reduced model for the parasitics seen by a driver of a net, using a PI model and a set of Elmore delays to each receiver。 The PI model consists of two capacitors and a resistor between them, with nearCap being the capacitor closer to the driver。 The oaElmore class represents the Elmore delays, which are the first moment of the impulse response of the interconnect parasitics from the driver to each receiver。 Undo is not supported for oaPiElmore objects。
