Abstract:
A method and system for compiling a representation of a source circuit including one or more source subchannels associated with portions of source logic driven by a plurality of clock domains are described. Each source subchannel may generate packets carrying signal data from one of the portions of the source logic. A representation of a destination circuit may be compiled to include one or more destination subchannels associated with portions of destination logic replicating the source logic. Each destination subchannel may forward the signal data via the packets to one of the portions of the destination logic. A switching logic may be configured to map the source subchannels to the destination subchannels as virtual channels to forward the packets from the source subchannels to the destination subchannels. A single queue may be configured to couple with the switching logic to record packets from the source subchannels into a packet stream for a delay period to distribute to the destination subchannels. The destination logic may emulate the source logic synchronized with the plurality of clock domains delayed by the delay period.
