Programmable hysteresis for boundary-scan testing |
摘要 |
Disclosed is a Boundary-Scan test receiver for capturing signals during board interconnect testing. The test receiver has a comparator with a first input to receive signals during board interconnect testing, and a second input to receive a reference voltage. A programmable hysteresis circuit is coupled to at least one of the comparator's inputs. The programmable hysteresis circuit may be configured to program a hysteresis voltage and/or a hysteresis delay, both of which help prevent the comparator from integrating signal noise.
