Through SRI's Generalized Emulation of Microcircuits (GEM) program, the Microcircuit Emulation Center supplies form, fit, function, and interface replacements for obsolete microcircuits. This capability supports production, redesign and sustainment requirements for the life of a weapon system. GEM devices can be used interchangeably with original microcircuits without changes to system documentation or test programs.

SRI’s Microcircuit Emulation Center is a government-supported, U.S.-based Trusted foundry. Once a replacement device has been produced, SRI remains a continuing source for the microcircuit.
