    Help me with power estimation of a digital circuit under ADS

    Re: mixed signal simulation Try EverCAD's ADiT for your mixed signal. They have ADiT (Turbo) for big-A. It can co-sim with NC-Verilog, VCS or modelsim. Or you can use EverCAD's ADiT-HDL and ADiT-Turbo. the website is www.evercad.com Check it out. I like it.. easy configuration/set up..

    Mid-range mixed-signal IC design tools

    Have you tried EverCAD's ADiT?

    Question about DPF (Device Parameter Format)

    Hello, I read that I can back-annotated the geometric device data to the pre-layout hierarchical netlist with a DPF (device parameter format) netlist. I can not find any syntax or site how I can create this DPF file. Do you have few samples of DPF files? Do you know any site where I can find...

    Mix Analog and Digital design verification??

    Try ADiT for mix analog and digital design verification. ADiT-VPI will hook ADiT to your favorite digital simulator (VCS, NC-Sim, Modelsim) and you can do co-simulation. If you don't have a digital simulator, then you can use ADiT-HDL and ADiT to do mixed-signal verification. It is easy to set...

    what file must needed by hsim?

    hmm.. no..

    verilog-a, how to simulate?

    You can also try EverCAD's ADiT. It now supports Verilog-A.

    Hsim output waveform ?

    nwave　analog waveform I know NASSDA's HSIM can output Veritools' fast file format also. But somehow Nassda's support team does not really know how to set it up.. Hopefully they are aware of their own features.. I usually use Undertow from Veritools.. Cheap and can read pretty much all the...

    What's "Adit" tools

    adit spectre Here is the list of ADiT tools ADiT-SPICE: Spice like simulator for accuracy ADiT-Turbo: fast-timing simulator for speed ADiT-MOT: macro simulator for huge capacity (ie. mainly for RAMs) ADiT-VPI: links ADiT to VCS,Verilog-XL, NC-Sim and Modelsim for cosim ADiT-FLI: links ADiT to...

    Comparision Spectre HSpice HSim

    I thought HSIM plus was just repackaged HSIM with "options" I heard one of the options were SPICE netlist parser.. How are you going to run simulation if you don't purchase that option! hehe.. Probably my misunderstanding.. but I thought it was funny. I heard HSPICE improved its speed by 25%...

    Using Tanner Tools for Analog IC design

    I guess you are talking about ADiT-Turbo. I tried ADiT-Spice, which is definitely a lot faster than HSPICE. I heard that new HSPICE release will have 25% speed up.. Is it true? You are the first one to say that HSIM/POWERMILL/ADITSPICE is slower than HSPICE!! haha. LESS ACCURATE (MAYBE), BUT...

    Using Tanner Tools for Analog IC design

    I was at DAC. 1. ADiT I saw window version of ADiT. If I use my 3Ghz machine with window version of ADiT, then it would be awsome! I saw their new viewer too. a lot better than before.. Again on the windows version! ADiT-Turbo can be used with Tanner. Since Tanner does not have a fast-timing...

    Opinions on using Cadence Ultrasim for simulation

    Re: C@dence Ultr@sim I heard from my Japannese contact that UltraSim is dead there. Gave up at benchmark too. Try ADiT, if you are currently using HSIM, Nanosim, or UltraSim. You will see how accurate and faster it is. http://www.evercad.com/successstories.html I tried SmartSpice and it ran...

    Beginner - Layout techniques

    beginner ic layout What tools are you using? If you are using Cadence, then you probably find tutorials in there. I used their tutorials and followed step by step and it was pretty useful. =)

    Using Tanner Tools for Analog IC design

    Hi Tanner Tools are for Analog IC Design. But I think they only support Windows. (The Mars rover/NASA used Tanner tools. 8O ) But I use ADiT. (www.evercad.com) with Cadence's Analog Artist. Because I like how ADiT can go from Spice mode to Fast circuit mode to mixed signal mode. Try it ADiT...

    Best tools for AMS design

    vcd ams designer spectre http://www.evercad.com/images/ADIT_Datasheet.pdf I can only find the datasheet for ADiT. The datasheet does not really mention ADiT-VPI but it is the new stuff that I am using.
