Ambrish, Thanks for pointing this problem out. I am sure we will address these issues as our discussions on AMI improvements continue. I would like to ask you a couple of questions about the usage of "default". 1) Considering your statement that "we have used the word Default to specify the value for that model/simulation", what would you say is the difference between the typical value of a range and the default? 2) Your statement "we have used the word Default to specify the value for that model/simulation" opens up the question I asked a several weeks ago about parameter strings. Remember, my impression about the specification was that the entire .ami file was supposed to be passed into the DLL's parameter string and consequently the DLL was supposed to parse it and extract the values from it. Your statement that "we have used the word Default to specify the value for that model/simulation" seems to underline that thinking, because it seems that you are saying that the DLL will extract the default value and simulate using that. In this case, the EDA tool could modify the original .ami file's default values before passing it to the DLL according to the user's wishes for each specific simulation. On the other hand, if this was not the intent, in other words, if the DLL is supposed to get only a subset of the .ami file in the parameter string, I am still looking for a description in the AMI specification that explains how to formulate that subset.

Defaults, generally mean that if there is no value provided, the tool will use the default value. In the spec, we have used the word Default to specify the value for that model/simulation (particularly in the reserved parameters section). There is also confusion because we have defined the format for declaring the parameters at 2 places for the reserved parameters (one with format, one without). Please refer to the attached document to see the changes that I am proposing to the parameter section. Thanks, -Ambrish. -----Original Message----- From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Muranyi, Arpad Sent: Tuesday, August 18, 2009 6:51 PM To: IBIS-ATM Subject: [ibis-macro] Re: IBIS AMI Specification Questions/Proposal Bob, Thanks for posting this summary of the problem. I read trough the attached file and I am not sure what the reasons are for these inconsistencies. In order to make the right decisions, I feel we need to ask those who wrote these portions of the AMI spec to find out what was their intent. Authors, please speak up... Thanks, Arpad ======================================================== -----Original Message----- From: ibis-macro-bounce@xxxxxxxxxxxxx [mailto:ibis-macro-bounce@xxxxxxxxxxxxx] On Behalf Of Bob Ross Sent: Tuesday, August 18, 2009 5:11 PM To: IBIS-ATM Subject: [ibis-macro] IBIS AMI Specification Questions/Proposal All: This is being sent out per the issue raised at the Aug. 18 meeting concerning parser interpretation of the AMI Spec. The ibischk5 parser with the -ami flag will check the syntax of the <file name>.ami file. The attached document shows several forms for <parameter_name> that are in the specification. Some of the forms imply a restricted set of parameters, but then this is contradicted by the example at the end. This implies that some parameters are really optional and not excluded according to the syntaxes given. The propposal is simply to make all parameters at least optional, and some required according to a draft Table 4 that is NOT in the specification. Do the choices in Table 4 look reasonable?
