摘要： A data bus of a DVD+RW recorder between a DSP and a SDRAM usually needs a multilayer wiring board. In order to simplify the layout of the wiring board of the data bus there is provided a method for connecting at least a first and a second integrated circuit by providing the first integrated circuit having a plurality of first logical I/O ports physically arranged in a first order at the periphery, and providing the second integrated circuit having a plurality of second logical I/O ports physically arranged in a second order at the periphery, wherein each first I/O port is to be connected to one of said second I/O ports. The first and second I/O logical ports are connected independently from the first and/or second physical order, so that connection lines do not cross each other.
