Abstract
A test system formatter may include a programmable drive circuit configurable to operate in any of a plurality of drive modes, each mode corresponding to a different combination of drive signals or drive timing markers or both, and a programmable response circuit configurable to operate in any of a plurality of strobe modes, each strobe mode corresponding to a different combination of strobe signals. The formatter may also include multiple drive channels and/or multiple response channels, each channel being formed, e.g., of an event logic interface and a corresponding linear delay element. The drive channels provide signals to the drive circuit to be used to generate drive signals or drive timing markers or both. The response channels receive from one or more pin-electronics comparators response signals used to generate fail outputs. The programmable drive and response circuits are configurable to route signals through multiple channels in parallel.
