Traditional logic testing relies on blasting pattern after pattern at the inputs, trying to exercise combinations to shake faults out of logic and hopefully have them manifested at an observable pin, be it a test point or a final output stage. It’s a remarkably inefficient process with a lot of randomness and luck involved.

I could have written the sequence of the title in reverse order, but no, design is the one which initiates the need of a particular flow and the flow needs support of EDA tools to satisfy that need. It’s okay if the design is small; some manual procedures and workarounds/scripts may be able to perform certain jobs. However, as the design… Read More
Electronic Design Automation, or more affectionately known as EDA, is a relatively young $5B industry with a very colorful upbringing, one that I have experienced firsthand, I’m very grateful for, and is an honor to write about. Today EDA employs an estimated 27,000 people! There is a nice EDA Wikipedia page which can be found here… Read More
The problem:To move dual-port SRAM library and macros from a 40nm process to a 28nm process. In addition to all the changes between two different foundry processes, the 28nm rules are disruptive and incompatible with the previous rules. The memory corecells (foundry-specific) would also need to be completely replaced.
Current… Read More
For an industry committed to constant innovation, changes in any part of the design flow are only slowly adopted, and only when absolutely necessary. Almost 10 years ago, it became clear that shrinking process technologies would bring a massive growth of layout and mask data—rougly 50% per node. This avalanche of data seriously… Read More
