aDUT motivations Main features of the DUT board The DPU directly interfaces the DUT board through the main system bus. Fixed types of memory chips A solution is required to add versatility to the DUT!! The answer is aDUT with the following key elements Board based on an FPGA (Actel A3P600) Simple proccesing capability JTAG interface AMBA bus 8

Work in Progress !! aDUT architecture The aDUT FPGA implements a SoC AMBA bus JTAG block AMBA interface TAP controller Memory controller Embedded RAM Watchdog Block 10 Realibility Features

Due to the criticality of the AMBA bus and the JTAG interface, in the aDUT architecture: Built-in Self-Test ensuring the device integrity Watchdog timer. Flip-flops are triplicated according to the Triple Modular Redundancy scheme. 11 Implementation details Results obtained to resources consumption of the A3P600 FPGA Type of resource Used

Core 2432 out of 13824 17,59 % IO (W/clocks) 101 out of 270 37,47 % Global (Chip + Quadrant) 3 out of 18 16,67 RAM/FIFO

4 out of 8 16,67% USER JTAG 1 out of 1 100% 12 JTAG Command Generator This new block is included in the DPU Allows the communication between the DPU and the aDUT board through the JTAG interface Acts as master in the JTAG base command-response protocol, performing read/write operations into the memory chips contained in

the aDUT board Commands: Responses: aDUT_c_Ping aDUT_r_ACK aDUT_c_Write aDUT_r_FAIL aDUT_c_Read

aDUT_r_Data aDUT_c_Memory_Test 13 System Testing (I) ProASIC3 Starter Kit from Actel aDUT SoC Aeroflex Gaisler/Pender XC3S-1500 DPU + JTAG Command Generator JTAG clock 1 MHz (tck)

We expect to end the board manufacturing this month Planned to go to Jyvaskyla accelerator (Finland) in December 14 Conclusions A board based on FPGA and designed to test the in-orbit radiation effects on different microelectronic was presented The design is based on mature and validated architectures AMBA JTAG Its modular design allows the easy integration of new memory types, such as DDR and FLASH memories The design is optimized for the selected FPGA family but can be quickly migrated to other FPGA devices

The small sized allows an easy integration in more complex systems The aDUT concept can be used as massive memory unit only by increasing the number of memory chips and changing the JTAG interface for high rate protocols such as Spacewire 15 ACKNOWLEDGMENTS This work has been supported by: CAM/UAH (Ref.
