peekBits(signal: Bits, stale: Boolean): BigInt
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.

run(testFn: (T) ⇒ Unit): Unit
Runs of tests are wrapped in this, for any special setup/teardown that needs to happen.
Runs of tests are wrapped in this, for any special setup/teardown that needs to happen. Takes the test function, which takes the module used as the testing interface. TesterContext setup is done externally.

def
setTimeout(signal: Clock, cycles: Int): Unit
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.
