Paper Abstract

This paper describes how placement and routing with manual intervention to improve the digital signal performance. According to studying and analyzing the features of Field Programmable Gate Array (FPGA) devices which include chip architecture and timing characteristics, a new approach is presented that some key logic modules can be relocated reasonably with manual intervention after completing successful place-and-route automatically. An example is given to illustrate this method. In this example, in order to improve remote sensing Charge Coupled Device (CCD) camera performance, signal-skew and delays among CCD driving timing signals must be controlled accurately and easily. This method can make CCD driving timing signals obtain the zero-skew which means tCO (clock to out) values for all these signals are equal, and finally hardware tests are carried out and experiment results are measured precisely by oscilloscope.
