Abstract
A novel diagnostics and verifiable input/output (DVIO) channel may reduce fixed diagnostic circuitry and allow standard input/output channels to be repurposed as diagnostics for specific deployments. The DVIO channel may include a digital input sub-channel and a digital output sub-channel, with each sub-channel including basic protection and diagnostic circuitry for performing basic diagnostics. The two sub-channels may be used independently of each other, and they may also be coupled together to create an enhanced digital input or digital output channel, which is capable of performing more advanced diagnostics such as output readback or test pulse generation, for example. Multiple DVIO channels may be coupled together to create a multiple-channel digital input or digital output with redundant signal paths. In this way the input/output resources may be configured to meet the specific needs of a given application, and minimize the test and diagnostic circuitry required in traditional implementations.
