Description

CapExt is a software package for simulating capacitive touch that was designed from the ground up to be as easy to use as possible, while returning accurate results. With CapExt, you can ensure optimal touch performance before the first prototype.

Key Features

Shave weeks to months off of your design cycle with CapExt.

  • Easy to use
    • Runs on any Windows computer
    • Import standard design files such as Gerbers or DXF files
    • From Gerber to simulation results in under 5 minutes
  • Find and fix noise/crosstalk issues
  • Simulate the effect of moisture/water on your touch design
