[IBIS] RE: BIRD127.4: IBIS-AMI Typographical Corrections CORRECTED

Mahbubul,

You are correct, the model specific parameters are optional.
There may be a little confusion about this because in one
sentence the IBIS v5.0 specification says (pg. 143):

                             The file must have 2 distinct
| sections, or sub-trees, 'Reserved_Parameters' section and
| 'Model_Specific' section with sections beginning and ending
| with parentheses.

but on the same page, the next paragraph says the following:

| The 'Reserved_Parameter' section is required while the
| 'Model_Specific' section is optional.

Page 144 reiterates the optionality:

| (Model_Specific | Required heading to start the
| | optional Model_Specific section

so the intent is clear, but the first statement can be
confusing. This is one of the many things that what we
clarified in BIRD 127 for the next version of the spec.

Some EDA vendors may have taken the position based on the
first sentence on pg. 143, but I believe that is incorrect.

Thanks,

Arpad

Hello,
I have an AMI (attached) file for a RX that does not require any Model Specific parameter. Because, it is a self contained adaptive RX. So I left out the Model Specific parameter section. I have one simulator works with this model as expected. Two other simulators are having problem with this omission.

bird127.4 states -
"
|*              ending with parentheses.  The file may also contain another
|*              section or sub-tree named 'Model_Specific', beginning and
|*              ending with parentheses.
"
I read that as 'Model_Specitic' parameter section is optional.

Could you help me with clarification?

Sincerely,
Mahbubul Bari

(ironically enough, an incorrect version of the revised BIRD127.4 was sent out earlier; the corrected version is enclosed and is posted to the website)

The enclosed revised BIRD 127.4, IBIS-AMI Typographical Corrections, is posted on behalf of Arpad Muranyi of Mentor Graphics, Inc.  It will be discussed at the next IBIS Open Forum teleconference.

A complete list of BIRDs and BIRD status updates is available at http://www.eda.org/ibis/birds/.
