    HSPICE on PC and SPARC - different results

    Today, i even found that the results on P4 and Athlon are different! Both simulations are on Win 2K and model, netlist, simulation card are the same. I use HSPICE because of its proved accuracy and good convergence. In fact, I tried HSIM before, it is several times faster than HSPICE, but for...

    How to design a nice PLL?

    I have a little experience before. I joined a team to decide 125MHz CRC for ethernet. For some kinds of PD, if the matching of device is not good, there will be no pulse for very small phase difference. So people will put dummy NAND gates to match the delay inside the PD to reduce the dead zone

    HSPICE on PC and SPARC - different results

    Both files are the same, model, simulation card, circuit netlist. Everything is the same, in the same directory

    h/s/p/i/c/e L*I*C may/be useful

    would you tell me how to use it? do i need to start a license server or just copy the file into hspice.exe directory. thanks a lot

    HSPICE on PC and SPARC - different results

    I am using BSIM3.3 Model. I think the models are OK since I get same result for some other circuit in AC and transient analysis. But, for switching capacitor circuit, I get different results.

    HSPICE on PC and SPARC - different results

    ultrasim waveform awaves Anyone tried to run simulation on PC and SPARC? I tried and find that the results are different for switching capacitor circuit. Anyone has same experience? Thanks
