Bill Martin: clarifying Accellera’s IP Tagging 1.0 Standard

Tuesday, April 30th, 2013


Bill Martin, President/VP of Engineering at E-System Design, sent a thoughtful response to my April 25th blog regarding Accellera’s recently released Soft IP Tagging 1.0 standard. I appreciate the time he took to clarify the ongoing need for such a standard.


I was part of VSIA when Kathy Werner was driving the IP tagging standards. I am happy this one from Accellera is now out [Soft IP Tagging 1.0] and the various users can determine how best to apply it. It is a large step forward, but only one of many required.

Unfortunately, the current system for IP tagging can be easily ‘hacked’ to disable any tracking. Simple text editing the source code and removing a few lines can completely remove the tag. But Accellera’s standard is a good first step to hone the standard; understanding how it works and does not work for various constituents.


IP Tagging 1.0 standard: Holy Grail or TMI?

Thursday, April 25th, 2013


Here’s a rhetorical question regarding Accellera Systems Initiative’s newly announced Soft IP Tagging 1.0 Standard: Is this the holy grail of IP or simply way too much information?

The question seems a fair one given the description in Accellera’s April 15th Press Release: “Normally, control of a third-party IP source is lost once the block of IP is licensed, unlocked, or otherwise made available in clear code. IP Tagging 1.0 facilitates a data-driven method to tag a block of IP and track ‘where used’ for applications such as ownership, royalty calculations, and recognition. It also facilitates the implementation of version identification for applicable bug fixes and errata and allows tracking of other data.”

This last bit, the part where bug fixes can be applied, is clearly the stuff of holy grails. But that first bit – reversing the “normal” loss of control regarding the source of third-party IP after it’s licensed and unlocked – isn’t the stuff of TMI, too much information revealed about something that may be better off kept under wraps?


SIP: And in other news …

Thursday, April 11th, 2013


Years ago, an editor/mentor advised me never to cover legal battles between companies in this industry. He’d always say, “There’s no good to be had from covering this stuff. The story’s always so much more complicated than anybody every fesses up to, so just don’t go there.”

So, how about this? Shall we accentuate the positive and decentuate the negative? You think that’s stupid, naive, not gritty enough? Well, y’all know where to go if you want to accentuate the negative and decentuate the positive. Y’all know where to go if you want the rumors and innuendo.

If, however, you’d rather start off your week with something a bit more upbeat, stick around.


IP @ DAC: a session a day keeps the doctor away

Thursday, April 4th, 2013


Despite grumbling to the contrary, even some that I myself put forth in a blog earlier this year, there will indeed be a daily dose of IP information doled out at DAC in Austin in June. If you’re interested in IP, DAC 2013 actually promises to be quite informative. You can arrange your schedule so as to attend a single significant session each day devoted to various aspects of IP with all of its promise and particulars.

Here’s your DAC planning guide …
