Hi All,

I need to create power grid library (Technology node: 130nm-90nm) for rail analysis. I found that I must first generate QRC extraction file (.tch) for this purpose, and before that I must create an ICT file. ICT file is a textual process-description file and can be generated by any text editor. However, ICT file must be filled with some process information which I do not know how I can obtain. Can anyone help me.

Thanks

In the worst case, if you cannot find either IRCX, or ICT, or ITF etc.. you must get the the DRM {Design Rule Manual}, and associated linked documents for the specific foundry/process.
Get as much info as possible - on the metal-stack ::
Metals, dielectrics, passivation, substrate, etc.. with details on height, thickness, erosion-data, BIAS, trapezoidal cross-section data, WEE {Wire-Edge-Extension -if any} / rho/sheet-res {may not be static constant, could be a function of 3 different parameters like - spacing, width, density}, TC1, TC2, {width dependency if any}. Min-spacing, min-width of metals are also required for modeling..
For dielectrics, get info on dielectric-coefficients, type=conformal/planar, side-wall, bottom and air-gap etc.[if at all] - you should be able to create an ICT file manually.
Complete details is covered in QRC Techgen Reference Manual.
There are sample ICT files available with latest QRC {PVE 12.1.X} installation..
