Description: Seven-Segment is a pure combinational circuit, usually small-scale special IC, such as 74 or 4000 Series devices only for decimal BCD decoding, digital systems, however data processing and operations are binary, so the output expression hexadecimal, in order to meet the decoding of the hex number display, the most convenient way is to use a decoding program to implement in the FPGA \ CPLD. In this study, as a 7-segment decoder, the output signal LED7S 7 g, f, e, d, c, b, a, high in the left, low on the right. For example, when LED7S output for " 1101101" digital tube 7 paragraph g, f, e, d, c, b, a, respectively 1,1,0,1,1,1,0,1. Access the high level segment shiny, so the digital display " 5" .
