2 months agoHi, boundary scan logic allows also to change data direction (enable/disable tri-state drivers) and set output state of pins. You can e.g. read or write memory devices connected to FPGA pins. There are various BSDL tools available, I'm e.g. using TopJTAG Probe with USB-Blaster and Altera FPGA.
