properties associated with it, such as bus type (type of bus the pin interfaces

to, e.g., AMBA APB, or CoreConnect PLB), interface type (master or slave), func-

tion type (the function implemented by the pin, such as read, write, or inter-

rupt), operation type (e.g., request, acknowledge), data type (e.g., address, data, or

instruction), and pin group (to indicate grouping of pins in the same interface). A

specialized language is used to specify these properties for the pins. By compar-

ing the properties on pins, it can be determined whether the functionality of a

real pin falls within ...
