    Comparing two layouts

    Could you expand what you mean by comparing? As @dick_freebird says, you can do polygon comparison with some scripts. DRC check would be one of them. You could also build your own tcl/skill script to compare each rectangle paint of one design against another design. Think of it as "moving"...

    maximum length that can be used in 180nm technology

    I imagine you can use 360nm transistors. I don't know why you say the design is old? Will all your transistors be 360nm, in that case I think you should redesign. It's ok to have an onversize transistor if you want to limit the current going through that transistor.

    When & How to give numbering for authors, while writing Research work to journal.

    Re: When & How to give numbering for authors, while writing Research work to journal. You got it right! That's how I do it

    If you could invent ANY appliance for your home, what would it do?

    Watch the Jetsons.... I think I'd invent Rosie the household robot. Everything else exists in one way or another: - automatic vaccumm cleaners -- chck - dishwasher - check - electric doors/windows/blinds - check - robot mowers - check - robot pool cleaners - check - automatic...

    VLSI Architectures open problems

    If it's an open problem it usually means it's difficult, so.... 3-4 months is hard to say. suggestions: - Non Von-Neuman architectures: Analog computing, Neuromorphic - Scheduling ... always a problem, never a solution - Low Power / Low Energy ... think of it as more battery - Probabilistic...

    Arduino UNO as a Programmer

    This video shows how to program an ATTiny. Maybe similar steps need to be followed to program an ATmega https://www.youtube.com/watch?v=30rPt802n1k Good luck!

    want tsmc 0.18um, 0.5um and 0.35 um CMOS technology file

    Most SPICE simulations check for the MOSFET model number. I'd imagine PSPICE ( a well known spice simulator ) will fail (or at least warn) if the Compact MOSFET level model is not compatible with the simulator. Check the log for any of these errors. According to this page, PSPICE supports...

    Test Pattern Generator Design

    AFAIK, BIST can use digital structures such as ads-ee mentioned, LFSR. Some of them also use physical parameters to create PRBS such as PUFS (https://en.wikipedia.org/wiki/Physical_unclonable_function) I was looking (and thinking on taking) this course form Udacity on hardware verification...

    Test Pattern Generator Design

    LOL. I never meant to say that your question was silly. I meant that MY question to you was silly. Excuse me if I sounded rude. You can use Verilog to drive spice or Verilog to drive Verilog. I would read this thread for example: https://www.asic-world.com/verilog/art_testbench_writing2.html...

    Density and uniformity on small ASIC in 180nm

    The density rules allow are aimed for DFM (Design for Manufacturability), so overall you should try to make them happen. See this article. https://vlsicad.ucsd.edu/Research/Projects/t1_vlsi_dmi.html#1_I You don't need to fill them with "active" metal, you can usually 1) fill with metal and...

    Test Pattern Generator Design

    Silly question, do you mean a physical TPG or for simulation?

    want tsmc 0.18um, 0.5um and 0.35 um CMOS technology file

    What is the use for this technology files? Are you a potential buyer? a Student? or just for kicks. AFAIK, there are no accounts for educational purposes, it is only for serious buyers. If you want to do a small prototype, contact a Multi-Project-Wafer-Program MPWF such as mosis: mosis.com...
