ABSTRACT:
A method and system are described in a logic simulator machine for overriding a value of a net during execution of a test routine. A model of a logic design to be simulated is built utilizing the logic simulator machine. The logic design includes multiple nets. One of the nets whose actual value may be overridden is selected. A multiplexer is inserted into the model. The multiplexer receives as its inputs the actual value of the selected net, a control bit, and an override value bit. An override value is input into the multiplexer using the override value bit. The multiplexer outputs a current value of the selected net. The current value is thus propagated to other nets. The override value is propagated as the current value of the net instead of the net's actual value throughout execution of the test routine when the multiplexer control bit is set.
