// CXXRTL uses assert() to check for C++ contract violations (which may result in e.g. undefined behavior
// of the simulation code itself), and CXXRTL_ASSERT to check for RTL contract violations (which may at
// most result in undefined simulation results).
//
// Though by default, CXXRTL_ASSERT() expands to assert(), it may be overridden e.g. when integrating
// the simulation into another process that should survive violating RTL contracts.
