Abstract

The technology and design flow used for developing two advanced Systems On Chip is described. The chips are JPIC, an image compression ASIC using JPEG2000 standard, and GR712RC, a dual core LEON3FT processor. Both chips employ the Rad-Hard-By-Design RadSafe™ technology, and are implemented on a standard 0.18μm CMOS technology. Each chip size is 12×12mm, integrating more than 40 million transistors. RadSafe™ technology provides very high immunity to all radiation effects. The library was designed for high immunity to radiation and high reliability. It includes standard cells, SRAMs, all-digital DLL and I/O cells. It was proven on several test chips, demonstrating TID immunity in excess of 300Krad, proven SEL above 80MeV and SEU at 20μ2 cross section (10-12 errors/bit/day). Logic design includes EDAC, memory BIST, and techniques to minimize soft errors. Logic synthesis was performed with large timing margins and scan insertion. Physical synthesis includes a robust power grid, careful placement of I/O cells, immunity to process sensitivities, robustness to thermomechanical stress and packaging reliability. A custom 240 pins CQFP ceramic package for GR712RC was optimized for mechanical stress, hermeticity, improved supply connection for reduced impedance, and robustness to handling. A custom 208 pins PQFP plastic package was designed for JPIC.
