My career started out by designing DRAM circuits at Intel, and we manually sized every transistor in the entire design to get the optimum performance, power and area. Yes, it was time consuming, required lots of SPICE iterations and was a bit error prone. Thank goodness times have changed, and circuit designers can work smarter … Read More
There have always been good reasons to port designs to new foundries or processes. These reasons have included reusing IP in new projects, moving an entire design to a smaller node to improve PPA, or second sourcing manufacturing. While there can be many potential business motivations for any of the above, in today’s environment… Read More
By any measure analog circuit design is a difficult and complex process. This point is driven home in a recent webinar by MunEDA. Michael Pronath, VP Products and Solutions at MunEDA, lays out why, even with the assistance of simulators, analog circuit sizing and tuning can consume weeks of time in what can potentially be a non-convergent… Read More
It has been my pleasure to interview Harald Neubauer, CEO of MunEDA. A veteran of the EDA industry, Harald cofounded MunEDA in 2001.
What brought you to the EDA industry?
Well, I always wanted to found a tech startup and was developing and evaluating various business ideas together with my later cofounder Andreas. Soon after we got… Read More
There is an old saying popularized by Mark Twain that goes “There are three kinds of lies: lies, damned lies, and statistics.” It turns out that no one can say who originated this saying, yet despite however you might feel about statistics, they play an important role in verifying analog designs. The truth is that there are large numbers… Read More
The commonly advanced reason for IP reuse is lower cost and shorter development time. However, IP reuse presents its own challenges, especially for analog designs. In the case of digital designs, once a new standard cell library is available, it is usually not too hard to resynthesize RTL to create new working silicon. For analog… Read More
Every year at DAC, in addition to the hubbub of the exhibit floor and the relatively short technical sessions, there are a number of tutorials that dive in depth into interesting topics. At the 56th DAC in Las Vegas this year, MunEDA offered an interesting tutorial on Analog IP migration and optimization. This is a key issue for large… Read More
The letters “PVT” roll of the tongue easily enough, belying the complexity that variations in process, temperature and voltage can cause for analog designs. For semiconductor processes, there are dozens of parameters that can affect the viability of a design. It would be easy enough to optimize a circuit with only one or two varying… Read More
At the beginning of every project the one of the first questions that ought to be asked is whether there blocks from previous designs that can be reused. On the surface this seems pretty obvious. The wrinkle in this is that reusability varies a lot based on the design type and the effort that a team is willing to expend to bring a design… Read More
When working on an analog design, after initial design specs have been met, it is useful to determine if the design meets specs out to 3 or 4 sigma based on process variation. This can serve as a useful step before going any further. It might not be a coincidence that foundries base their Cpk on 3-sigma. To refresh, Cpk is the ratio of the… Read More
