Boundary scan architecture analog extension |
摘要 |
A method and apparatus provides an analog mode of operation of a standard test access bus interface based on a standard Boundary Scan architecture which is limited to use of digital signals. Circuits are included in the interface which enable this sharing of data paths at separate time intervals defined under instruction control for processing analog and digital signals thereby providing a hybrid capability without any increase in the number of lines required by the interface. |
