Patent 7379859 was granted and assigned to Mentor Graphics on May, 2008 by the United States Patent and Trademark Office.
Serializing and deserializing circuits are provided on an emulator circuit board to group input and output signals of programmable logic devices for routing through a cross point switch. In one instance, the input and output signals of the programmable logic devices are time-multiplexed signals of virtual interconnections. The cross point switch can be configured for static or dynamically scheduled operations.
