Antenna infromation for Hard Block

tswong

I am wondering whether anyone knows how to generate the antenna information for the hard macros. As far as I know, it can be generated those information through abstractor generator, but I do not know how to pass the antenna data for calculation.

  • Hi tswong

    There is a very good tutorial located at $CDSHOME/tools/dfII/samples/tutorials/abstract. It includes a section on generating antenna info. Maybe it can help you. The tutorial guide is located at appendix E of $CDSHOME/doc/abstract/abstract.pdf.

    Please also take note of the techfile requirements for generation of antenna info:
    COS solution 11207834

    Thanks for your info! Do you have any idea on defining antenna rules inide virtuoso chip assembly router?

  • Hi TS

    In vcar environment, please go to "Define->Properties->Layer" to define antenna info for each layer. You can go to "Report->Specify->Antenna Rules" to view the violations. COS 11222750 might also be useful for you. It gives an example of a doFile that checks for antenna violations.
