Abstract
The present disclosure relates to an apparatus () for joint test action group (JTAG) and scan emulation, the apparatus includes a controller circuitry () that is interfaced to a target integrated circuit (IC) () for testing the target IC, the controller circuitry having one or more serial peripheral interface (SPI) devices (--) operating in master mode and slave mode. The controller circuitry () operates the one or more SPI devices (--) to switch between a first mode and a second mode dynamically to emulate JTAG and scan test functionality. The controller circuitry facilitates reusing the one or more SPI devices located in the controller circuitry to emulate JTAG and scan test interface protocols without any additional hardware requirements.
