V2.2 | Sim-emu 6.02 Configurator

Mobile networks authenticate a SIM by sending a random number (RAND) to the card. The SIM uses its secret Ki and the RAND to calculate a signed response (SRES) using the A3 algorithm. In theory, the Ki should never leave the carrier's database.

The most significant internal change is the with a parallel SAT solver for constraint checking. This allows v2.2 to validate complex interdependencies (e.g., “if Port A > 100MHz then Bank B must be in low-power mode”) in under 200ms. sim-emu 6.02 configurator v2.2
