  • Cadence ELC Biphase Flip Flop Characterization

    Has anybody ever characterized biphase flip flops using ELC before? Im having problems with floating registers, as ELC asserts the second clock before the first, the second register takes the value from the first register (which is floating), and thereby yields a random output, causing the smulation...

  • Simple yet tricky: How to instance an entire library?

    Halo, This may be real simple, but how can I instance the symbol views of an entire library into a schematic? I need a method simpler than having to individually instance all of the symbols from the library. I suppose I will have to do it that way if there is no other option. I need to do this in order...

  • ELC memory macro characterization

    Hi All, I need some help for characterizing memory block generated by a memory compiler, which provides a spice model for the macro and a .lib file charatrized for nominal voltage. I am not really sure, how I can characterize a memory block with ELC. As I understand from the user guide, a gate file may...

  • Re: ELC doesn't simulate anything

    Hi, I have exactly the same problem. How did you specifically solve the problem? Here is my elccfg file ########################### #Specify the environment variable settings to use for characterization. EC_SIM_USE_LSF=1; EC_SIM_LSF_CMD=""; EC_SIM_LSF_PARALLEL=10; EC_SIM_TYPE="spectre";...

  • boolean cell description format

    I'm trying to use Encounter Library Characterizer to characterize a 4-ported register cell. Apparently ELC can't figure out what the logical description of the cell is. I believe I can tell it what the cell does using the db_gsim -bool command, however I don't know what the format is. Here...
