The parasitic resistance extraction tool based on Klayout

Dear all,
Here is chipR.
Which is based on Klayout, I use it to extract chip's metal parasitic Resistance.
Also, it can extract PCB's metal parasitic resistance.
Maybe it is useful for you.

The result matches to other finite element method's one. Its advantage is that it allows designers to extract metal's resistance more than one port.

Thank Matthias and his Klayout.

  • Wow! thanks for lot for providing this.

    I could not find a license - only mentioning that it's free for use at home. What specifically is meant by "at home"?

    I also need to say that parasitic extraction is a hot topic for open source EDA. Eventually the goal was to integrate this with device extraction, so a full extracted netlist becomes available.

    Kind regards,

    Matthias

    Hi,
    By now, I have not any idea about a license. It seems that there are many types of licenses in the world.
    I am confused by them. So I write the words "free for personal use at home" just because of the clear meaning.
    "personal "-->not for business
    "at home"--> not for company

    the parasitic extraction is useful in both IC design and PCB. especially, in ultra-sub-micron-meter (~<200 nm, for example, 0.18um, 90nm, 55nm...). the metal path's parasitic resistance & capacitance play an important role. many popular EDAs have been developed some extraction tools.

    I find there is very little free tool to do this. So I try to do a simple tool.
    This "chipR" uses one simple and different algorithm to extract the parasitic parameters.
    I compare this tool's result to other time-consuming EDA or finite element methods. It has a good match result.
    It is fast, accurate, easy.

    I apply it to my chip project to do some intuition analysis. I find it very useful.

    I like it becomes a free EDA tool.

    Of cause, It based on the great Klayout!
    Thank your Klayout.

  • I received one message telling me the bad link to download chipR.
    Now the link is repaired.

    Also if any problem during using this tool please let me know.
    Thanks.
