Is there an updated version of an Application Note from 2007, AN17582, "Failure Mode and Effect Analysis (FMEA) Implementation for CSD" ? AN17582 was written for PSoC 1 as it lists PSoC Designer version 4.4.
Cypress now offers Built-In-Self-Test (BIST) in the CapSense Component. Is this BIST an implementation of the recommendations in AN17582?
Any updated or additional recommendations to self-test Capacitive capabilities on PSoC 4 that might identify keys not functioning in field applications would be appreciated.

Hi GrCa_1363456
Yes. BIST is an implementation of these concepts. With the latest component, CapSense V7.0, there are several test that are available such as
-checking RAM structure integrity,
-RAM widget integrity,
-checking sensor short to ground, VDD and other sensors,
-parasitic capacitance of sensors and shield,
-VDDA measurements
-External capacitors measurements.
All these tests can be performed by running the CapSense_RunSelfTest API. Please note that the "Enable self-test library" option must be enabled for these APIs to be active.
You can refer the latest component datasheet for more information.
