In the 1960s the Worboys committee suggested that road traffic signs should be predominately symbolic, because they are clearer from a distance. Only eight countries that replied had a sign representing older people (table). The Namibian sign illustrated a generic picture of a pedestrian with the words “elderly people” below (fig 2). This avoids stereotyping, but the sign may not be as quickly ...

Symbolic evaluation is the execution of software and software designs on inputs given as symbolic or explicit constants along with constraints on these inputs. Efficient symbolic evaluation is now feasible due to recent advances in efficient decision procedures and symbolic model checking. Symbolic evaluation can be applied to partially implemented descriptions and provides wider coverage and g...

We present a symbolic simulation based veri cation approach which can be applied to large synchronous circuits A new technique to encode the state and input constraints as parametric Boolean expressions over the state and input variables is used to make our symbolic simulation based veri cation approach e cient The constraints which are encoded through parametric Boolean expressions can involve...
