PLL Macro Model Wizard

slim5

Hi,

  I am trying to use the PLL Macro Model Wizard to create a macro model for a VCO and I used the information from the document file titled "Virtuoso Spectre Circuir Simulator RF Analysis User Guide" (Product version 7.2, December 2009) as my guide. When I got to the Figure 16- and clicked OK, I got this error "Unable to find VCO plugin in similator library directory. PLL Macro Model will be disabled."

  Does anyone know what is the cause of this error and how I should go around to fix it?

   Thank you!

Regards,

Su Lim

  • Hi SU Lim,

    One quick thing -

    Can you set the suggested environment variable in your cshrc file as -

    setenv _pll_global_spectre_path <spectre_install_dir>/tools/lnx86/spectre

    and then source the cshrc and  restart the virtuoso session

    Or

    set the following command in .cdsinit file or in CIW,

    setShellEnvVar(“_pll_global_spectre_path=<spectre_install_dir>/tools/lnx86/spectre”)

    and restart the virtuoso session and see if this helps.
