SENSE is the only simulation software that can perform an Equivalent Circuit extraction of any touch sensor automatically.

The equivalent circuit (EC) extraction system generates the EC of a specified touch sensor pattern in the form of a netlist. The values of the resistance and capacitance (RC) elements of the circuit are obtained from local area simulations around predetermined regions of interest.

The produced netlist can be used together with a SPICE simulator or SENSE itself to analyse the performance of a touch sensor. Possible outcomes of this analysis can be:

  • Voltage response

  • Acquisition time

  • Charge time

  • Raw counts
