Abstract: Method and system for application specific integrated circuit (ASIC) simulation, wherein the ASIC includes plural logical elements is provided. The method includes, monitoring transitions at an output of a logic element of the ASIC; checking if the transition is to an unknown value (X); verifying if the unknown value is based on a design error; forcing the output of the logic element to a known value if the unknown is an unwanted condition; propagating the known value to logic elements in the ASIC; and releasing the known value after a next command.

Abstract: Method and system for testing a network device is provided. The system includes, a test program running on a host system that communicates with the network device through a bus functional module; and a test module that includes a packet counter that counts test packets that are received from a buffer and written in a memory of the test module; and an idle timer that counts time that has expired after a last test packet has been received by the memory module of the test module; wherein if the packet counter value exceeds a threshold value then all test packets residing in the memory of the test module are sent for testing network device logic and if the idle timer expires at any given instance, then all the test packets in the memory of the test module are sent for testing network device logic.
