Abstract
A JTAG tester includes a JTAG controller in a PCI slot of a PC, a port multiplexer, a programmable power supply, and drive and compare logic, which tracks V . The tester reads and blows information and configuration fuses on the silicon using the JTAG port. The tester pipes the JTAG port into a 1-to-N multiplexer, where N is the number of sockets being tested in parallel. The multiplexer is different from conventional multiplexers in that it allows selection of any combination of sockets, not just any one of the N sockets. Thus the same data can be driven into any combination of devices for parallel programming of fuse registers. Data being read out is read one device for separate evaluation via the single port back to the controller PC.
