  1. Space Qualification Test(RTSX-SU) Larry Harzstark The Aerospace Corporation January 18, 2006

  2. Space Qualification • Objective is to expose flight parts to extended life test conditions to obtain long term reliability data

  3. Space Qualification Details • 304 RTSX32SU and 154 RTSX72SU life-tested for 6000 hours • Design based on NASA test design but modified to decrease the length of the timing paths • Half the parts are life tested at 125 ºC, with the other half at –55 ºC • VCCI=5.0V, VCCA=2.5V, and undershoot less than 1.5V

  4. Space Qualification Design Summary • Utilization Post-Combiner device utilization: SEQUENTIAL Used: 1080 Total: 1080 (100.00%) COMB Used: 1800 Total: 1800 (100.00%) LOGIC Used: 2880 Total: 2880 (100.00%)(seq+comb) IO w/ Clocks Used: 168 Total: 170(46 CMOS) (47 PCI) (74 TTL) CLOCK Used: 2 Total: 2 HCLOCK Used: 1 Total: 1 • Fan out • 26 nets have fan out of 24 • Timing Analysis • Setup time @ 125 ºC, VCCA = 2.25V, VCCI = 4.5V, -1 grade • I/O clock max frequency = 67 MHz • Array clock max frequency = 85 MHz • Hold time @ -55 ºC, VCCA = 2.75V, VCCI = 5.5V, STD grade • Shortest path has 0.51 ns margin

  5. Space Qualification Fuse Utilization F=> 2540 Antifuse between freeway & output track G=> 0 Antifuse between output track & 2nd, 3rd, & 4th freeway on the net H=> 319 Antifuse between two horizontal tracks V=> 76 Antifuse between two vertical tracks W=> 25 Antifuse between horizontal segment & 2nd freeway on the net(old-style freeway) X=> 4873 Antifuse between horizontal segment & freeway B=> 1130 Antifuse between Local Track and input S=> 1332 Antifuse between output track & input(semi-direct) I=> 10006 Antifuse between horizontal segment & input K=> 1572 Antifuse between input & horizontal NCLK0 or NCLK1, or QCLK 21873 Total Dynamic Antifuses J=> 11299 Antifuse between input & horizontal NVCC or NGND M=> 211 Antifuse for I/O configuration options Q=> 8 Silicon Signature afuse in silicon signature words T=> 0 Antifuse between output track & input that is used early in programming sequence to tieoff floating output track Y=> 1836 Antifuse between horizontal segment & vertical NVCC or NGND Z=> 630 Antifuse between freeway & horizontal NVCC or NGND 13984 Total Static Antifuses 35857 Total Antifuses
