Returns set of clocks associated with sinks of the signal
Returns set of clocks associated with sources of the signal
Returns the current value on a wire.
Returns the current value on a wire. If stale is true, returns the current combinational value (after previous pokes have taken effect). If stale is false, returns the value at the beginning of the current cycle.
Read the value of a clock.
Writes a value to a writable wire.
Writes a value to a writable wire. Throws an exception if write is not writable.
Writes a value to a clock.
Sets the timeout of the clock: the number of cycles the clock can advance without some non-nop poke operation.
Sets the timeout of the clock: the number of cycles the clock can advance without some non-nop poke operation. Setting cycles=0 disables the timeout. Setting cycles=1 means every cycle must have some non-nop poke operation. Resets the idle counter associated with the specified clock.
Advances the target clock by one cycle.
Returns the stack trace elements of parent threads.
Returns the stack trace elements of parent threads. If currently in the root thread, returns empty. TODO: refactor this, figure out how to do this in a structurally cleaner way
Returns the value associated with the key in a per-test map.
Sets the value associated with a key in a per-test map.
