JTAG External Modules (JEM_DIMM/SODIMM™) for the DDR2/DDR3 Memory Socket Test
The ATPG tools of each of these JTAG test platforms can generate tests with the advanced diagnostics for the socket pins failure detection, as well as sensing analog voltages on the individual power pins (such as Vdd, Vddq, Vddspd and Vref). The JEM_DIMM/SODIMM™ module TAP channel can be simply combined with any board TAP chain or used as a separate TAP. An advantage over other similar solutions is that the JEM_DIMM/SODIMM™ module connection setup can be done either with an external TAP cable or completely in-circuit, without any cabling! The modules design is ready for cascading multiple DDR2/DDR3 memory socket testing. Each JEM_DIMM/SODIMM™ module features hot-swap capability.
Our JEM_DIMM/SODIMM™ module product line consists of almost full spectrum of the modern socket types, more than 20 types right now, each additional DDR2/DDR3 memory socket type is also accessible upon request.
It's worthwhile to emphasize that the usage of any DIMM socket test modules of our competitors needs a customer have a merger software, because these DIMM modules are described by the netlist. In the contrary, we're giving the DIMM socket BSDL file instead, so there is no need to modify the BUT netlist.
