Title:
CIRCUIT DIAGRAM CAD DEVICE
Document Type and Number:
Japanese Patent JPH01147672
Kind Code:
A
Abstract:
PURPOSE:To easily confirm the connection state between signal lines covering plural pages with a circuit diagram CAD device by plotting and displaying the relation among a signal line covering plural pages, an unconnected signal line and each page. CONSTITUTION:An inter-page connection data origination part and a cross- reference adding part originates inter-page connection data by an instruction given from an input part and based on the circuit data stored in a circuit data memory part and store this data in a memory part. Then an inter-page connection display data origination part reads out the inter-page connection data in response to the input and originates the inter-page connection display data as shown in a diagram in accordance with the unconnected state and the connected state of the output only, etc., to display the originated data at a display part. Thus it is possible to visually confirm the inter-page connection state and to improve the production efficiency of a logic circuit.
