MUX CLK40 and output data by new chip [9-DEC- 04] This picture shows that the original data bus (BUS A31-0) and additional data bus (BUS B31-0) can be processed correctly. This test pattern is; BUS A31-0 pattern = up counter; , , ,… BUS B31-0 pattern = down counter; FFFFFFFF,EEEEEEEE,DDDDDDDD,… ….. slot0slot1slot2slot3slot0slot1slot2slot3 Reference : Probing Test pattern generating Test board

Summary of ASIC test Packaging and test board assembly are finished. Result of functionality test seems fine, but not completed yet. Functionality test will be finished in this month.

GOL test setup GOL test board: It can be mounted on Vertex2- pro board via PMC connector Vertex2-pro evaluation board: =Vertex2-pro interface board Vertex2-pro has integrated hi- speed deserializer. OE/EO converter: Agilent evaluation board GOL test full setup GOL Vertex2pro EO converter Optical fiver

FPGA program overview GOL test program is based on the xilinx evaluation source. Vertex2-pro generates test vector, serializes, and comparisons between generated vector and GOL output vector. generating test signal comparisonserialize (integrated) display (LED&LCD) deserializer (GOL) Vertex2-pro program

Test step 3Gbps→1.6Gbps (cupper wire) V2P RocketIO Vertex2pro TED Vertex2-pro test Board 1.6Gbps (optical fiver) V2P Agilent EO board Agilent OE board 1.6Gbps (optical fiver) V2P GOL test board Agilent OE board Cupper wire setup [26 Oct.] System test, Developing GB-ethernet protocol, Changing the link speed* 2.Optical fiver setup [12 Nov.] Optical component test 3.GOL test *Changing the link speed Vertex2-pro test board has 156MHz crystal for the V2-pro maximum speed. In our case, we need 1.6Gbps.

Summary of GOL test Test setup is ready now. Gigabit Ethernet protocol for GOL is developed.
