Circuit design simulation

A system for simulating a circuit design, the system comprising:

• means for providing access to a circuit design block for a plurality of simulation tools;
• means for updating a run status associated with the circuit design block in response to the block being simulated by one of the plurality of simulation tools;
• means, responsive to a first simulation tool request for access to information regarding a circuit design block, for checking a run status of the block, the run status being indicative of the block being simulated;
• means for simulating the block as a function of the run status;
• and
• means for returning results of the simulation to the simulation tool.

A system for simulating a circuit design, the system comprising:

• an interface arrangement adapted to:
• provide access to a circuit design block for a plurality of simulation tools;
• update a run status associated with the circuit design block in response to the block being simulated by one of the plurality of simulation tools;
• in response to a first simulation tool request for access to information regarding a circuit design block, check a run status of the block, the run status being indicative of the block being simulated;
• simulate the block as a function of the run status;
• and
• return results of the simulation to the simulation tool.

A program storage device, comprising:

• a processor;
• a processor-readable medium configured with instructions executable by the processor for demoting a page in virtual memory by performing the operations of:
• providing access to a circuit design block for a plurality of simulation tools;
• updating a run status associated with the circuit design block in response to the block being simulated by one of the plurality of simulation tools;
• in response to a first simulation tool request for access to information regarding a circuit design block, checking a run status of the block, the run status being indicative of the block being simulated;
• simulating the block as a function of the run status;
• and
• returning results of the simulation to the simulation tool making the first simulation tool request.
