Abstract
An indeterminate state representative of a metastable state is inserted into an output signal of a circuit representation responsive to the circuit representation receiving a metastable triggering event during a register transfer language (RTL) simulation. The simulation view of the RTL has been modified to ensure that the indeterminate state is propagated through the circuit representations regardless of the input on which the indeterminate state appears. The indeterminate state is maintained for a programmable amount of time and responsive to expiration of the amount of time, the output signal is set to a random binary value.
