need to access the first registers to I/O pads using db commands

abhaska

Hi all

 I need to access the first registers  to i/o pads using db commands... i've used procedures calling technique.. i'm able to access the

instances upto 2nd level.. but unable to further proceed  through the path as the instance are more between i/os and registers.

I've used a pointer  for the further access of the instances by recalling the procedure.. but the infinite loop prob occurs..

Can anyone pls help me in this regard..

Thanks

Arun

    Hi Arun,

    If you're talking about logic depth, there's a script in the gifts directory that might be helpful:

    <install_path>/share/fe/gift/scripts/tcl/userAddMenuPullInstsToIos.tcl

    The script provides a way to "trace and pull" instances connected IOs (or pins on IO cells) close to the IO they're connected to.  It is similar conceptually to the native "placeJtag" functionality, but is more brute force in the way it works.

    If you're talking about 2nd level of hierarchy, please do reply and let us know as that is a different challenge altogether.
