When TSMC and Mentor Graphics held a joint seminar for mutual customers to go over new DFM requirements at 45/40 nm, two customers basically asked the same question, “What do you mean by mandatory?” Of course, TSMC wasn’t going to stand over them and say, “Mandatory means mandatory, what part of mandatory don’t you understand?” … Read More

Apart from the coolness factor, my main motivation was corporate mail support that was absent in Gphone, plus the fact that I got the iPhone for free when my wife upgraded hers. The difference is day and night… Read More

If you are a TSMC customer, no doubt you have heard TSMC is requiring lithography and planarity analysis for all 45nm designs. Their website says customers can either run it themselves, or contract TSMC services to do it. The most cost-effective way would be for the customers to run it themselves, but some might not have the resources… Read More


So, Why Not Just Write Better Rules?

In my submission about TSMC making some DFM analysis steps mandatory at 45nm (see “TSMC’s DFM Announcement”), I ended with a question about why the foundries can’t just write better design rules (and rule decks) to make sure all designs yield well. Here’s my take on this complicated question.… Read More
