Data routing and multiplexing architecture to support serial links and advanced relocation of emulation models

Abstract:

Disclosed herein are systems and methods of compiling resources of a programmable emulation system to execute an emulation process, to emulate a logic system, such as an application-specific integrated circuit (ASIC), currently being tested and prototyped, and then revising, transforming, and moving the compiled instructions sets to inexpensively, quickly, and dynamically adapt to unavailable resources, which may be due to previously allocation to a different emulation job, or for fault tolerance. Relocation of the resources that will execute the emulation job (i.e., "footprint") may refer to the remapping of a compiled footprint to a revised set of resources, defining a revised footprint. Fault tolerance may refer to support for working around faulty hardware components of the emulation system.
