Abstract :
Heterogeneous, distributed hardware/software cosimulation techniques using the backplane method encounter complex interface protocols for simulator communication and synchronization, limiting their adoption or abstraction. We simplify the dynamics of backplane cosimulation to the properties of a Kahn Process Network (KPN), such that tokens of the KPN are interpolated events. This simplifies the backplane API and reduces the coordination problem to a parameterization of token update rates. The performance of this method is reported on a timed ISS model for Freescale HC12 microcontrollers (TExaS) coordinated with a Spice (Ngspice) circuit simulation.
