  • Patent number: 7912693
    Abstract: Systems and methods are provided for verifying respective configuration data values for programming configuration memory cells of an integrated circuit device such as a programmable logic device (PLD). Each configuration memory cell controls an input of a corresponding initialization value from a file in response to a selectable assertion of an initialization signal of a test bench during a logic simulation of the PLD. The file structurally associates the configuration memory cell with the corresponding initialization value. A current value of one or more of the configuration memory cells is written with the respective configuration data value via a configuration port of the PLD during the logic simulation. Each configuration memory cell compares its initialization and current values in response to a selectable assertion of a check signal of the test bench. A mismatch error is output in response to a difference between the initialization and current values of one or more of the configuration memory cells.
