Figure 6 shows a 7-segment decoder module that has the two-bit input c1c0. This decoder produces seven outputs that are used to display a character on a 7-segment display. Table 1 lists the characters that should be displayed for each valuation of c1c0. To keep the design simple, only three characters are included in the table (plus the blank character, which is selected for codes 11). The seven segments in the display are identified by the indices 0 to 6 shown in the figure. Each segment is illuminated by driving it to the logic value 0. You are to write a VHDL entity that implements logic functions that represent circuits needed to activate each of the seven segments. Use only simple VHDL assignment statements in your code to specify each logic function using a Boolean expression.
