ABSTRACT:
The present invention provides a method for designing LSI including a logic circuit equipped with a scan circuit without generating a hard-macro library for the scan flip flops constituting the scan circuit. According to the method, first netlist NL1is converted into second netlist NL2by adding scan circuit including scan flip-flops. Order data for connecting scan chain of the scan circuit is extracted from the second netlist NL2. Such second netlist NL2is converted into third netlist NL3including only hard-macros, and the third netlist NL3is laid-out by re-ordering the scan chain so that the newly generated order data for is stored temporally. Fourth netlist NL4including scan circuit formed by scan flip-flops of soft-macros is generated on the basis of the stored order data, then the fourth netlist NL4is converted into fifth netlist NL5by substituting the scan flip-flops of soft-macros for standard cells of hard-macros. Finally the generated fifth netlist is laid-out without re-ordering the scan chain.
