A method of configuring a programmable integrated circuit device with a user logic design includes analyzing the user logic design to identify unidirectional logic paths within the user logic design and cyclic logic paths within the user logic design, assigning the cyclic logic paths to logic in a first portion of the programmable integrated circuit device that operates at a first data rate, assigning the unidirectional logic paths to logic in a second portion of the programmable integrated circuit device that operates at a second data rate lower than the first data rate, and pipelining the unidirectional data paths in the second portion of the programmable integrated circuit device to compensate for the lower second data rate. A programmable integrated circuit device adapted to carry out such method may have logic regions operating at different rates, including logic regions with programmably selectable data rates.

An isolator assembly is disclosed. The assembly comprises a laminate consisting essentially of a block of homogenous material and a set of electrical contacts. A first die is coupled to a surface of the laminate. An isolation barrier is located entirely above the surface of the laminate. A second die is coupled to the laminate. The second die is galvanically isolated from the first die by the isolation barrier. The second die is in operative communication with the first die via the isolation barrier and a conductive trace on the laminate. The first die, the second die, the laminate, and the isolation barrier are all contained within an assembly package.

Methods and apparatus are provided for allowing components such as buffers, multiplexers, ingress cores, etc. on a device such as a programmable chip to configure themselves based on parameter information. In some examples, self-configuring components obtain parameter information from adjacent components. In other examples, self-configuring components obtain parameter information from a system environment or a processor register. Component self-configuration can occur at a variety of times including preprocessing, simulation, and run-time.
