Methods, systems and media for functional simulation of noise and distortion on an I/O bus

A machine-accessible medium containing instructions effective, when executing in a data processing system, to cause said data processing system to perform operations comprising:

• constraining one or more fields of a record based on one or more parameters of the I/O bus;
• determining a net delay value based on the one or more parameters;
• determining a final delay amount based on a delay buffer and the net delay amount;
• determining a value of a next bit to be sent to the I/O bus;
• and
• after waiting for the final delay amount, driving the bit on the bus to the next bit value.

A system for simulating noise and distortion parameters of an I/O bus, the system comprising:

• a verification environment, the verification environment being adapted to constrain one or more fields of a record based on one or more parameters of a design under test, the record having one or more fields associated with it;
• a bus agent of the verification environment, the bus agent being adapted to launch a time consuming method to simulate one or more parameters of the design under test;
• and
• the bus agent comprising one or more bus functional models, the one or more bus functional models being adapted to stimulate the design under test based on the simulated parameters of the design under test.
