Abstract
The design of logic for implementation in programmable logic array integrated circuit devices is facilitated by allowing various characteristics of modules in the logic design to be parameterized. Specific values for a parameter can be “inherited” by a logic module from other logic higher in the hierarchy of the logic design. Default values for parameters can also be provided. The user can design his or her own parameterized modules, and logic designs can be recursive, meaning that a logic module can make use of other instances of itself.
