Abstract

A system and method for connecting a running logic circuit simulation to a network running at a higher speed that includes a computer for receiving data packets from the network and storing the received data packets in a first buffer. The computer next transmits the received data packets to an electronic circuit in the logic circuit simulation at a slower speed. The computer also receives data packets from the electronic device under simulation, and stores the data packets received from the electronic device under simulation in a second buffer. The computer then transmits the data packets received from the electronic device under simulation to the network at a higher speed.
