Simpler MEMS Models for ASIC Designers

Some time back, we took a look at the library of mechanical elements in Coventor’s MEMS+ tool for building MEMS device models. In the “be careful what you wish for” category, making it easier to connect elements into models meant that engineers started connecting more elements into models, and the models got bigger.

Big models can stress a tool out, resulting in slow results and resource starvation.

Well, they’ve just released version 4 of MEMS+, which at the very start, addresses those concerns, enabling quicker handling of more complex models.

But there’s a much more subtle way that they’ve addressed the needs of ASIC designers. Each MEMS element will need an accompanying ASIC to clean up the signals and abstract away a lot of the mechanicalness of the element so that electrical types – or, more likely, digital types – can understand the sensor outputs in their own language.

And, of course, you’re going to want to get started on that ASIC design as soon as possible. But the whole purpose of the ASIC is to turn messy sense element behavior into clean outputs, and in order to do that, you need to know exactly what messy signals you’re going to start with. And you don’t want to wait until the device is finished to do that; you want to model the behavior ahead of time.
