A hardware or software test that runs independently of user interaction and allows the system to test itself. It is typically used to verify functionality of a system or perform diagnostics and usually runs at power up time. However, it can usually be commanded to run if needed. An common example is a RAM test that is executed at system power up time to verify read/write accesses.

As a provider of custom mixed-signal ASICs, Triad can implement BIST in both the analog and digital domains. Triad’s re-configurable ASIC technology allows BIST implementations to be modified, through a 1-mask change, as your overall system requirements evolve throughout your product life cycle.
