Abstract
The invention provides parametric modules called Self Implementing Modules (SIMs) for use in programmable logic devices such as FPGAs. The invention further provides tools and methods for generating and using SIMs. SIMs implement themselves at the time the design is elaborated, targeting a specified FPGA according to specified parameters that may, for example, include the required timing, data width, number of taps for a FIR filter, and so forth. SIMs are called “self implementing” because they encapsulate much of their own implementation information, including mapping, placement, and (optionally) routing information. Therefore, implementing a SIM-based design is significantly faster than with traditional modules, since much of the implementation is already complete and incorporated in the SIM.
