"RH1020 Single Event Clock Upset Summary Report,"
Abstract:
This report summarizes the testing and analysis of "single event clock upset" in the RH1020 for Pass 6 parts. Also included are sample SEU-rate predictions and design recommendations for risk analysis and reduction. (.pdf  74 kbytes).
rh1020_tid.PDF "Qualification Total-Dose Test Results for the Actel RH1020 FPGA,"
Abstract:
This radiation test characterized and qualified the RH1020 FPGA to total-ionizing-dose radiation. A sample size of 5 programmed parts were exposed to gamma radiation from a cobalt-60 radiation source at 1X the specified radiation level (i.e., 300 krads{Si}) and then at 2X the specified radiation level, with all parts passing. The part is a radiation-hardened CMOS 2000-gate FPGA and is fabricated using the LMFS "RHCMOS-4EF" process merged with the Actel oxide-nitride-oxide (ONO) anti-fuse process, with LEFF = 0.8 µm, VDD = +5.0V, and ONO TEFF = 96 Å.

Summary of Heavy Ion Test on the Actel RH1020 Antifuse at BNL, May, 1998.  Two units of the RH1020 showed antifuse hardness to 6.0 Volts at Bromine.  (.pdf 14 kbytes).

Act1_SEU_Hardening.pdf K-Mod Flip-Flop SEU test results.  The K-Mod flip-flop uses 4 C-Modules in a mirror topology.  This results in an increase in the SEU LET threshold as well as a substantial decrease in the upset cross-section. (.pdf 12 kbytes).
Act1_SEL_BNL1198.PDF A1020B/TI and A1020Z (experimental) devices were tested for single event latchup (SEL) at BNL in Nov., 1998.  The SEL threshold for the A1020B/TI is < 22 MeV-cm2/mg.  No latchup was detected for the A1020Z up to an LET of 120 MeV-cm2/mg. (.pdf 10 kbytes)

A1020B_SEL_Report_BNL0199.PDF
BNL-Jan,99 Latchup Study.  This plot shows that a device left in the latched state (in vacuum) may exhibit runaway.  This resulted in the device currect exceeding 800 mA.
Complete latchup report for the BNL0199 A1020B SEL study.
Act1_Latchup_BNL0499.htm A set of Actel A1020B (Texas Instruments foundry) FPGAs were subjected to heavy ion tests at Brookhaven National Lab, using titanium, nickel, and bromine, at normal incidence.  Ion energies and ranges are detailed for each run in the table below.  Worst-case voltages were used for this part, VCC = 5.5 VDC.  This test is designed to compare SEL results obtained at BNL with a high energy facility, University of Michigan.
