Method and apparatus for a multipurpose configurable bus independent simulation bus functional model

An apparatus, comprising:

• first means for interfacing with a circuit to be tested;
• and
• second means for interfacing with the circuit to be tested;
• and
• each of said first and second interfacing means having a corresponding at least one or more means, respectively, for executing multipurpose data structure block test transactions with the circuit to be tested, said multipurpose block test transactions programmable by a user for said circuit to be tested.

An apparatus for testing a circuit, comprising:

• means for generating known expected data for testing a circuit;
• means for storing data from the circuit on data transactions with the circuit;
• and
• means for generating an operation code for execution by the circuit;
• and
• means for testing the circuit, said testing means being selected from the group consisting of means for bus arbitration, interrupt generation, parity error generation, data sequence generation, data packet timing control, bus interface type, bus device identification, bus device function, data bus width, bus timing specifications, data transaction identification, data direction type, and data transaction type.

An apparatus, comprising:

• a bus interface for interfacing with a circuit to be tested;
• a first multipurpose bus functional model device having a configurable block data structure including at least one or more of the following functional blocks:
• parameters, configuration, transactions, data capture;
• a first state machine in operation with said first multipurpose bus functional model device for interfacing with said bus interface and said circuit to be tested such that said circuit may be instantiated in a test bench environment along with said first multipurpose bus functional model device having a configurable block data structure;
• a second multipurpose bus functional model device having a configurable block data structure including at least one or more of the following functional blocks:
• parameters, configuration, transactions, data capture;
• and
• a second state machine in operation with said second multipurpose bus functional model device for interfacing with said circuit to be tested such that said circuit may be instantiated in a test bench environment along with said second multipurpose bus functional model device having a configurable block data structure.
