小白求教tluplus

tluplus是什么意思，怎么理解?我在学习lab_guide遇到"File—> Set TUL+"出现dialog box时选择的tluplus的文件有：..max_tluplus;..min_tluplus;..typ_tluplus;...map 想知道这些文件具体指的是什么意思，看不明白。

摘自icc user guide：
TLUPlus is a binary table format that stores the RC coefficients. The TLUPlus models
enable accurate RC extraction results by including the effects of width, space, density, and
temperature on the resistance coefficients. For details about modeling these effects in the
Interconnect Technology Format (ITF) file, see the StarRC documentation.
To use TLUPlus models for RC estimation and extraction, you specify the following files:
• The map file, which matches the layer and via names in the Milkyway technology file with
the names in the ITF file.
• The maximum TLUPlus model file.
• The minimum TLUPlus model file (optional). Specifying the minimum TLUPlus file is
necessary if the minimum and maximum operating conditions are different and the
TLUPlus models have derating factors. In that case, the minimum file must be specified
even if it is the same as the maximum file.

我的理解就是tluplus包含了你抽取RC所需要的一些参数，并且针对你不同的OC设置max和min的tluplus 文件

RC模型参数，在提取时用的。这文件是foundary提供的
