Hi Arpad,

In the templates I sent, you can see the node ordering that CDS uses in
our B-elements. I included them as comments right in the model file, so
you can see how it is set up. It would make sense to me to use this same
ordering, as we are providing the templates. It is attached below.

*  The terminals in an 8-terminal differential MacroModel are as
follows:
*      power = 1
*      outp = 2
*      ground = 3
*      input = 4
*      enable = 5
*      power_clamp_reference = 6
*      ground_clamp_reference = 7
*      outn = 8

Subject: [ibis-macro] Node ordering for IBIS buffer building blocks

Hello,

I have a question about the order of the nodes for the IBIS buffer
building blocks in the library.  What should be our convention?

1)  Should we follow the order of nodes as it is done in the
    HSPICE B-elements?
2)  Should we have any other ordering scheme?  For example, have
    the "digital" (i.e. control) nodes first, such as In_D, En_D,
    Rcv_D, and then the analog ports?
3)  Any other suggestions?

Thanks,

Arpad
