Abstract
Disclosed is a designed-circuit-verifying method for verifying an LSI or a wiring-substrate circuit with ease at the design stage of the circuit. An analysis based on simulation of a circuit allows electrical characteristics of a designed circuit to be detected at a design stage and compared with reference data. In accordance with a result of the comparison, an item to be corrected, the location of the item and other information on the item can be identified. In addition, since details of the correction can be displayed at an identified position on the designed circuit, the design of the circuit can be corrected. Thus, the design efficiency of the circuit can be improved.
Claims3
A designed-circuit-verifying method for verifying a designed circuit at a design stage before actually constructing the designed circuit, the designed-circuit-verifying method comprising the steps of:
- designing said designed circuit using circuit components;
- simulating reference data representing expected electrical characteristics of the circuit components composing said designed circuit;
- detecting simulated electrical characteristics of said circuit components and comparing said detected simulated electrical characteristics with said simulated reference data;
- identifying at least one of said circuit components to be corrected on a basis of a result of comparison of said detected simulated electrical characteristics of said at least one circuit component and said simulated reference data so as to allow the designed circuit to be corrected before actually constructing the designed circuit;
- displaying said simulated reference data representing at least one electrical characteristic of said circuit component employed in said designed circuit on a computer screen;
- fetching said detected simulated data of at least one electrical characteristic of said circuit component;
- comparing said fetched at least one electrical characteristic with said simulated reference data and forming a judgment on a result of comparison;
- and
- displaying the result of said judgment on said computer screen.
