Ken Martin - President and Professor of Microelectronics
At Snowbush, we focus on high-end analog and mixed-mode interfaces with wired channels; currently, we have significant and increasing activities (over 50 employees)
especially in the areas of high-speed serializers and deserializers, and high-frequency ADC-based AFE's. Practically all of our designs include significant amounts of
digital circuits for calibration and programmability, and require a mixed-mode simulator. We focus on system design as well as circuit design. In these applications
SMASH excels. Although we use many simulators at Snowbush, I personally have been using SMASH extensively for almost 6 years and exclusively for the last 4 years.
Like all simulators, SMASH has had problems; when these occurred, the support from Dolphin has been immediate and excellent. In addition, SMASH's compatibility with
other simulators and foundry provided transistor models has been significantly improved recently and these are no longer limitations. Some significant areas SMASH
excels in: operating point convergence (best I've encountered), mixed transistor/verilog simulation (some start-up time, but very powerful), and fast accurate
simulations (top-of-the-class for prediction of distortion). Perhaps even more enabling: SMASH's AKO capability makes Monte Carlo simulations possible and simple, even
when foundry matching information is not available. Another enabling capability, that has been used extensively at Snowbush, is the C-modelling using the ABCD approach
(for behavioral DAC's, ADC's, S/H's, PGA's, digitally-controlled oscillators, etc.). I personally prefer SMASH over all other alternatives.
