Lansdale

Lansdale is a company based in Tempe, AZ that specializes in the emulation of military grade components using BiCmos devices through their Generalized Emulation of Microcircuits (GEM) program. They aim to combat the problem of obsolescence in military aircraft by providing high reliability subsystems and components. However, concerns have been raised about the lack of Change Control and Configuration Management in the GEM program, which may lead to catastrophic failures in the systems they are used in.

The Semiconductor Industry Association has expressed concerns about the GEM program, citing unfair competition and the use of different technology without conforming to best commercial practices. Despite efforts to address these issues through meetings, presentations, and publications, no significant changes have been made. Lansdale has performed characterization testing on GEM devices compared to original devices, highlighting electrical differences. However, the re-use of standardized part numbers for GEM emulated devices has raised concerns about the principles of Configuration Management. Attempts to bring about change within industry committees have been unsuccessful, and a task group was formed to rewrite the definition of device type in MIL-PRF-38535 to address these concerns.
