Piped MNS Simulations

Specifying CAN_PIPE (the default) in your usersimulators file for MNS enables IC-CAP to take advantage of the tune mode built into the MNS simulator. This mode permits changing parameters of a simulation without requiring the simulator to be relaunched. This greatly reduces the time required for an optimization which has all simulated targets within 1 setup. Whenever the setup is changed, the simulator is stopped and restarted with the new resulting netlist. Thus, an optimization that has multiple simulated targets from different setups must stop the simulator and restart it at each iteration as it switches between setups. The performance of this second scenario is the same as if the non-piped mode were used.
