    Calibre pex is not creating .pex and .pxi files.

    Hi, i am running calibre pex for post layout simulation. After extraction I want to do the post layout simulation using the spectre and not from the config view. It requires three files one is pex netlist and two other files are with .pex and .pxi extension. The later two files are not...

    RF testing of three port device with two port VNA.

    Thank you so much for answering the question. Do I need to buy some 50 ohm termination loads as well for proper calibration?

    RF testing of three port device with two port VNA.

    Ok. So terminating one load with 50 ohm and taking measurement from other and then repeat the process with changing the ports is the best way for measurement? Thank you.

    RF testing of three port device with two port VNA.

    Thank you so much for answering the question. My device is a phase shifter which uses a RC poly phase filter, it uses two differential signals to generate four 90 degree apart signals. if one differential signal is not there, PPF wil not work as far as I know. Can I just use an external balun...

    RF testing of three port device with two port VNA.

    Hi, I need help regarding testing my RF IC. I have designed a phase shifter which has differential inputs and single ended output. The VNA in my lab is a two port VNA for single ended input and output. Is there a way to buy an input balun or if I design one on the PCB, can I use that to input...

    [SOLVED] TSMC65nm Bondpads and ESD.

    HI, For bond pads and ESD you have to ask the foundry from where you got the kit. I did the same.

    Parasitic inductor extraction using PEX in TSMC 180nm and running netlist through terminal.

    Thank you so much for answering the question. I did as you saiid and I am getting another error as"......./ ABC.pex.netlist" 134: Expression is missing a terminating quote character.". Should I edit the netlist to fix it?

    Parasitic inductor extraction using PEX in TSMC 180nm and running netlist through terminal.

    Hi, I am doing parasitic inductor extraction using Calibre PEX, but inductors are unable to be mapped in calibre view since there is no cell present for parasitic inductor in TSMC 180 nm library. So simulation using config view is not giving correct results. I have the pex netlist with...

    MOM capacitor issue in TSMC 0.18um.

    Hi everyone, I have installed TSMC 180nm process for IC design. While designing the circuit we need to add license key for MOM capacitor given by foundry. I have the license key but the PDK utilit tool is giving error 'No setting file: Install PDK first' while I am putting the license key. I...

    [SOLVED] TSMC65nm Bondpads and ESD.

    Hi, I am using TSMC65nm for my circuit design. I am unable to find library for bondpad and ESD. Do I have to design it by myself, or are they provided by foundry? Thank you

    TSMC65nm DFM errors.

    Hi, I am designing an analog circuit in TSMC65nm process. I am having some DFM errors while running drc related to enclsure, distance etc. Is it a good idea to flatten the mosfet and fix these errors? Since all of these are related to mosfet structure. Thank you very much.

    HFSS integration with Cadence.

    Hi everyone, For my work I have to design a balun. For that I need to integrate HFSS tool with virtuoso. Can anyone please provide me any documentation on that? I need to smulate balun in HFSS and get layout in virtuoso. If there is any way of designing balun in spectre, please tell me. Thank you.
