Abstract:
1. A circuit design support device for designing a layout of electronic components on a circuit board to prevent the components from becoming a noise source or exceeding a predetermined temperature, the support device comprising: a noise generation level information adding means for adding noise generation level information a component library; a first component locating means which includes a component position detecting section for detecting a position of a component on the circuit board, a component position voltage distribution detecting section for detecting a voltage level at the position where the component is located, a noise generation level comparing section for comparing the voltage level detected by the component position voltage distribution detecting section with the noise generation level in the component library, and an error informing section for indicating an error when the voltage level detected is greater than or equal to the noise generation level in the component library; a heat generation level information adding means for adding heat generation level information to the component library; and a second component locating means which includes a component position detecting section for detecting a position of the component on the circuit board, a component position heat distribution detecting section for detecting a heat level at the position where the component is located, and a component locating section for locating the component on the circuit board based on the heat level, wherein the design of the layout of the electronic components on the circuit board is based on at least one of voltage distribution information provided by the first component locating means or heat distribution information provided by the second component locating means.
