Abstract: A computer-based simulation system comprises a hardware model of a hardware interface having a transmission line; a test bench; and a simulator configured to simulate the operation of the hardware model based on the test bench for functional validation, including representing a reflected wave in a digital simulation to recognize the presence of a peripheral device at the opposite end of a transmission line.

Abstract: A method and apparatus for capturing data. A first latch latches data from a data source in response to respective rising edge transitions of a first clock signal. A second latch latches data from the data source in response to respective falling edge transitions of the first clock signal. A delay circuit generates a second clock signal that lags the first clock signal by a delay period and, in response to respective transitions of the second clock signal, a multiplexer alternately selects the first latch and the second latch to output data to a storage element. A pulse strobe circuit strobes the output data into the storage element in response to the first clock signal and the second clock signal being in different states.
