Cadence IC5.1.41 libInit.il

ag2888
Hi,

I wanted to know is it possible to overwrite the libInit.il file, which is specified in the project area by a local version of the same??
I am actually trying to load a user defined set of "modelPath"s for the analog design environment. So i have another skill script in my local area to do that (this is loaded using .cdsinit). But the libInit.il file in the project area, that is sourced whenever i open the library manager, overwrites the "modelPath"s by loading a script in the project area.

Any suggestions how this can be done?

Any other suggestions on how to add some default set of "modelPath"s for the ADE?

Thanks

  • Hi,

    I am facing the exact same problem currently, and did not yet find an answer - too bad that Andrew did not answer this question, it would have been very helpful.

    Is there a way that I can keep my customized path to the modelfiles ?

    One workaround I found is, to load first the "libInit.il" in .cdsinit BEFORE setting my custom path. By that the Virtuoso environment does not reload the "libInit.il" when a library is accessed the first time via schematic/layout/ADE.

    But this workaround creates some warnings when loading "libInit.il" via .cdsinit, and I am not sure why and if it is okay to call it during .cdsinit.

    Any better way to do it ?

    If you allow the libInit.il to load by "accessing" the library it would be much cleaner, for example: ddGetObj("library_name") in your .cdsinit before your own code for setting the model paths. I have employed this dummy access for this exact reason - I can't control the foundry code but I can force their code to load before my own settings.  A bit of a kludge but it works and does not require changes from the foundry to accommodate my requirements.
