The System Model was built to enable post-processing capabilities of the results that are extracted from SENSE's parasitic extraction algorithms. This way, you can get raw counts and directly compare with real world measurements.

One of the most common problems engineers are facing is that they don't always know how to interpret Capacitance, C,and Resistance, R, values. Although those are the basics of the capacitive sensing technology, simply knowing, for instance, the mutual capacitance of a node or the resistance of an electrode is not always enough to evaluate the performance of a capacitive touch sensor. That’s why we built the System Model approach, so as to enable post-processing capabilities of the results of C and R that are extracted from Sense's parasitic extraction algorithms.

By introducing a SPICE solver for the post-processing needs and a list of controllers (IC), you can connect the sensor with a chip of your choice and receive values that are very close to what engineers are used to see: voltages, currents and raw counts.

The System Model consists of 4 tabs: Controller, Sensor, System Configuration and Analysis modules.

  • Controller, which is a library of controllers described by their netlist, their configuration parameters and their PINS' functionality

  • Sensor, which is the netlist equivalent of the Physical Model

  • System Configuration, which is the interfacing between the Controller and the Physical Model of the sensor

  • Analysis, which contains Counts Analysis with the optional addition of conducted noise analysis.
