Fieldscale

Fieldscale provides state-of-the-art simulation software for companies involved in the touch sensor industry all around the globe.

With Fieldscale, companies can:

• Reduce product development cycle and decrease time to market.
• Validate the performance of the design against customer requirements and reach the optimal design substantially faster.
• Test virtually a variety of different components from SENSE’s library under different environmental conditions without manufacturing costly hardware prototypes.
• Access cloud resources and analyze touch sensor designs on system-level in unprecedented speed.

Fieldscale expands the boundaries of electric simulation as we know them today, enabling very complex simulations since 2015.

Software offered by Fieldscale

Fieldscale is the company behind SENSE.

SENSE is a state-of-the-art capacitive touch sensor cloud simulation software, for electrical design and analysis, built from ground-up to support the constantly growing demands of engineers for accuracy and efficiency.

It features the unique capability to build an overall system configuration that closely replicates real-world performances by analyzing the touch sensor together with the MCU as a system.

Fieldscale in STMicroelectronics Ecosystem

STMicroelectronics worked together with Fieldscale to bring the electrical models of the Touch Sensing Controller peripheral of STM32 MCUs in SENSE. Users need to simply select their STM32 MCU and the software will generate models for pin configurations, clock settings, and other parameters, such as charge and discharge cycles, among others. You can read our use case to see how an STM32 user can work with SENSE.

Traditionally, creating a capacitive touch sensing application is quite complicated and requires significant expertise. STMicroelectronics and Fieldscale simplify this process since engineers no longer need to produce multiple PCBs to see how a design works. They can validate the performance of an STM32 microcontroller and then they can implement their parameters into STM32CubeMX to write their application.

SENSE is essential for the STM32 microcontrollers' ecosystem.

Fieldscale enables STM32 users to select the Touch Sensor Controller module embedded in an STM32 MCU. They can configure its parameters and get virtually the equivalent circuit of any touch sensor in a netlist format. Then they can combine them together in a system level analysis to simulate the Raw Counts from the STM32 microcontroller just as they would be measured in the lab.

Before committing to building physical prototypes, with Fieldscale SENSE STM32 customers can validate the performance of their touch sensor designs by following simple steps:

• Design or import capacitive touch sensor layout as a standard DXF or Gerber file(s).
• Evaluate the Touch Sensor by extracting results about the Sensitivity, Capacitance and Resistance.
• Analyze the effect of any pointer touching at any location of the design, including finger, bare or gloved, and stylus.
• Identify and correct EMI related problems. Add RF conducted noise into the system, to simulate the testing procedure as specified in the IEC61000-4-6 standard, to evaluate the noise immunity of your system.
