Defining standard use cases ensures that the security posture of Caliptra in the final implementation is not degraded relative to the consortium design intent. Any bits in GENERIC\_INPUT\_WIRES for which a function has not been defined (in the Caliptra version that is being integrated) must be tied to a 0-value.

Defining standard use cases ensures that the security posture of Caliptra in the final implementation is not degraded relative to the consortium design intent. Bits in GENERIC\_INPUT\_WIRES that don't have a function defined in Caliptra must be tied to a 0-value. These undefined input bits shall not be connected to any flip flops (which would allow run-time transitions on the value). Each wire connects to a register in the SoC Interface register bank through which communication to the internal microprocessor may be facilitated. Each signal is 64 bits in size.
