The fundamental economics of the semiconductor industry are summed up in the phrase “fill the fab.” Building a fab is a major investment. With a lifetime of just a few years, the costs of owning a fab are dominated by depreciation of the fixed capital assets (the building, the air and water purification equipment, the manufacturing… Read More
I used my secret powers (being a blogger will get you a press pass) to go to the first day of the SPIE conference on advanced lithography a couple of weeks ago. Everything that happens to with process nodes seems to be driven by lithography, and everything that happens in EDA is driven by semiconductor process. It is the place to find … Read More
During DVCon I met with Steve Bailey to get an update on Mentor’s verification. They were also announcing some new capabilities. I also attended Wally Rhines keynote (primarily about verification of course, since this was DVCon; I blogged about that here) and the Mentor lunch (it was pretty much Mentor all day for me) on the… Read More
Formal verification can be used for many things, but one is to ensure that synthesis performs correctly and that the behavior of the output netlist is the same as the behavior of the input RTL. But designs are getting very large and formal verification is a complex tool to use, especially if the design is too large for the formal tool… Read More
Cavium designs some very complex SoCs containing multiple ARM or MIPS cores at 32 and 64 bit. This complexity leads to major challenges in validating the overall chip architecture to ensure that their designs will meet the requirements of their customers once they are completed, with performance as high as 100Gbps.
Cavium have… Read More
Almost no design these days is created from scratch. Typical designs can contain 500 or more IP blocks. But there is still a big difference between the first design for a new system or platform, and later designs which can be extensively based on the old design. These are known as derivatives and should be much easier to design since… Read More
Often as we move down the process node treadmill, new challenges appear that we didn’t really have to worry about before. Often, these challenges require addressing at a number of different levels: the process, the cell libraries, the design, the EDA tools that we use.
One well known example is the problem of metal migration.… Read More
Most mixed-signal design teams don’t use data management. Well, that’s not entirely true, everyone has to do data management of some sort, it is just that it is often very ad hoc, often done by some vaguely systematic way of doing file naming, using email to keep track of changes, no access control and so on. This leads… Read More
Embedded NVM technology based functions can be implemented in large SoC designed in advanced technology nodes down to 28nm, as there is no requirement for extra mask levels, like when integrating Nand Flash, negatively impacting the final cost. And it is also possible to integrate One Time Programmable (OTP) to store trim and … Read More
Wally Rhines gave the keynote at DVCon yesterday. He started out with a game of “name that graph” which was unfortunately a bit spoiled since when the names were revealed the first line was off the top of the screen. But he extrapolated several trends such as the decreasing number of fabs (the current trend is that there… Read More
