Lance, I would like add a comment to your #2 below. While all tools may not be able to 'fully' comply to a standard, it is far better than proprietary solutions many may be proposing. The correct approach would be to stick to a standard and gradually add the missing features in all upcoming versions of a tool. If not, as Arapd mentions, might as well get rid of IBIS and go back 10-15 years. Is that your approach ? - Syed -----Original Message----- From: owner-ibis@eda.org [mailto:owner-ibis@eda.org] On Behalf Of Lance Wang Sent: Friday, November 10, 2006 9:27 PM To: arpad.muranyi@intel.com; ibis@eda.org; ibis-macro@freelists.org Subject: [IBIS] RE: [ibis-macro] Re: Your presentation at Asia Summit Hi, Arpad, I would like to point out two things: 1. Every standard needs to be a good helper to solve real industry problems. If not, there is no life for it. What if standard development speed is slower than technology growing speed, please remember there is no way to let industry wait for it. And the reality is we will never catch the technology growing. So, seeking other solutions is the common way industry will go. 2. Almost there is no tool(s) will exactly follow the standard(s). They may be behind with some features and may be ahead on some features as well. Do you think the AMS tools you used are exactly followed AMS standard?

Whether we make this practice legal in IBIS or not is not the issue. The issue is that these proprietary solutions only work with their corresponding proprietary tools. IBIS was started and motivated exactly to eliminate that situation. These requests you and Lance are talking about is going in the exact opposite direction of the original goal IBIS was invented for. We might as well get rid of IBIS and all other efforts to have any industry standard modeling languages (*-AMS) then...

I have said many times, that I believe AMS is the best technical solution for full circuit simulation of the newer technologies. Unfortunately, there are two barriers to AMS adoption: the first is getting the majority of the EDA vendors to make their best technology available in their SI tools, the second is the training of model creators to use a new languages. Progress is being made on both these fronts, but it is not as fast as I would like to see. Switching from the AMS issue to SPICE: I think we have all agreed that for us to try to create a standard for SPICE is not a fruitful activity. I do believe that SI tools should be able to pass parameters to SPICE syntax sub-circuits that represent the behavior of IBIS components. The SI tools that implement this feature will have to know the exact syntax (and parameter data types) to be used for each simulator that is supported. Correct me if I am wrong, but I believe that at least two SI tool vendors already have proprietary enhancements to allow parameters to be passed to SPICE sub-circuits.
