JTAG interface system for communicating with compliant and non-compliant JTAG devices |
摘要 |
A system and method for using standard JTAG protocol for testing protocol compliant and non-protocol compliant digital devices without altering the JTAG protocol or the non-compliant device. A specialized Test Access Port Controller controls and monitors the states applied to the non-compliant device in order to eliminate the PAUSE state in the non-compliant device and to limit the Run-Test/Idle state to one clock period.
