Abstract
The SEmulation system provides four modes of operation: (1) Software Simulation, (2) Simulation via Hardware Acceleration, (3) In-Circuit Emulation (ICE), and (4) Post-Simulation Analysis. At a high level, the present invention may be embodied in each of the above four modes or various combinations of these modes. At the core of these modes is a software kernel which controls the overall operation of this system. The main control loop of the kernel executes the following steps: initialize system, evaluate active test-bench processes/components, evaluate clock components, detect clock edge, update registers and memories, propagate combinational components, advance simulation time, and continue the loop as long as active test-bench processes are present. A Simulation server in accordance with an embodiment of the present invention allows multiple users to access the same reconfigurable hardware unit to effectively simulate and accelerate the same or different user designs in a time-shared manner in both a network and a non-network environment. The server provides the multiple users or processes to access the reconfigurable hardware unit for acceleration and hardware state swapping pu…
