ABSTRACT:
An adapter card in a computer system includes an application specific integrated circuit (ASIC) and a field programmable gate array (FPGA) coupled to the ASIC. Random data is provided to the ASIC logic function(s) by control of the FPGA, which is configured by a programmable logic device on the card and coupled thereto. The logic function(s) of the ASIC is then exercised with the random data, and the output is compared with expected output by the system to determine if there are any errors. The determination is made based on a signature produced by a multiple input shift register (MISR) within the ASIC, based on the output data from the logic function(s). The FPGA can then be reconfigured for normal adapter card functions.
