Methods and systems for building a simulation for verifying a design block, including efficient coordination of the control and validation of the operation of a first and second bus of the design block, with the first bus being an interface bus of a processor. An interface description is determined for a bus functional model of the interface bus of the processor. The interface description includes a synchronization bus for coordinating the bus functional model and a hardware description language (HDL) testbench. A hardware specification is generated that couples the first bus of the design block with the interface description, and couples the HDL testbench with the second bus of the design block and with the synchronization bus of the interface description. The simulation for verifying the design block is automatically generated from the bus functional model and the hardware specification.

Building a simulation of design block using a bus functional model and an HDL testbench

A method is provided for building a simulation environment. A first functional model is produced that emulates the interaction of a processor with a first interface of a bus for the processor as controlled by a first script. A second functional model is produced that is controllable to emulate multiple interfaces. The second functional model is controlled to emulate a second interface of an input/output peripheral by a second script. A third functional model is produced that emulates a memory subsystem. A simulation environment is automatically generated that simulates the design block for a programmable logic device. The simulation environment couples the bus to the design block and the first and third functional models, couples the second interface to the design block and the second functional model, and couples the first and second functional models via a synchronization bus used for synchronizing between transactions of the first and second scripts.
