Conclusions
• In this talk, we have presented considerations for selection
of ICs for space systems
– Technical, programmatic, and risk-oriented
• As noted, every mission may view the relative priorities between
the considerations differently
• We have also noted a specific type of example, that of
custom to semi-custom devices
• As seen below, every decision type may have a process.
– It’s all in developing an appropriate one for your application.
