Automated Pad Ring Generation for Programmable Logic Device Implementation of Integrated Circuit Design

摘要

In an embodiment, a method to automatically generate a pad ring for a programmable logic device implementation of an integrated circuit is contemplated. The pad ring that will be used in the integrated circuit itself may include pad logic (e.g. to support boundary scan and other forms of testing), custom driver/receiver circuitry, etc. The pad ring in the programmable logic device, on the other hand, may be predetermined as part of the production of the programmable logic device. The generation may include removing the pad logic and other pad-related circuitry from one or more design files that represent the integrated circuit, as well as mapping the input, output, and input/output signals of the integrated circuit to the available programmable logic device pads.
