In formal verification, case splitting consists of separately considering different cases.
In symbolic evaluation, case splitting introduces multiple paths where some variable has a different concrete value on each path. This allows more efficient reasoning about concrete values and can work past issues that would be hard for a solver to handle such as non-linearity, etc.
