LEAD FRAME DESIGN SUPPORT APPARATUS, LEAD FRAME DESIGN SUPPORT METHOD, AND LEAD FRAME DESIGN SUPPORT PROGRAM

摘要

PPROBLEM TO BE SOLVED: To improve the quality of waveforms and to reduce costs. PSOLUTION: A lead frame design support apparatus 10 measures a transition time of a signal waveform. The lead frame design support apparatus 10 calculates a distribution constant unit length on the basis of the measured transition time. Subsequently, the lead frame design support apparatus 10 divides a lead frame by the distribution constant unit length and calculates the division number of the lead frame. Thereafter, the lead frame design support apparatus 10 respectively calculates a wiring width on the basis of the quality of the signal waveform for each lead frame divided by the division number.
