Method and system for integrated circuit design and diagnosis

A method for displaying signal values at multiple time-frames comprising:

• identifying a plurality of storage elements in a signal path in a circuit;
• displaying a first storage element of the plurality of storage elements;
• displaying a first signal value carried on a first signal line coupled to at least one output of the first storage element at a first time-frame;
• displaying the first signal line;
• displaying a second signal value carried on a second signal line coupled to at least one input of the first storage element at a second time-frame;
• and
• displaying the second signal line.

A computer-readable storage medium having stored thereon computer instructions that, when executed by a computer, cause the computer to:

• identify a plurality of time-frames in a circuit, the plurality of time-frames being determined by a number of consecutive storage elements in a signal path in the circuit;
• receive a request to display signal values associated with a first storage element at a time-frame t;
• display the first storage element;
• display a first signal value carried on a first signal line coupled to an output of the first storage element, the first signal value being at time-frame t;
• display the first signal line;
• display a second signal value carried on a second signal line coupled to an input of the first storage element, the second signal value being at time-frame t−1;
• and
• display the second signal line.

A method for displaying a schematic diagram of a circuit showing multiple time-fine signal values across storage elements, the circuit having one or more loops, the method comprising:

• identifying a loop in a signal path, the loop comprising:
• a first element at a first time-frame;

• a first signal line coupled to an output of the first element and an input of the second element;
• and
• a second signal line coupled to an output of the second element and an input of the first element;
• displaying the first element;
• displaying the second element;
• replicating the first element at a third time-frame;
