The order for top_level. vhd is shown in Figure 5. 17. entity architect ure Figure 5. 17 top_level. vhd, as displayed in Project Navigator, ahead editing. The label in Figure 5. 17 contains an entity and an architecture section. The entity section defines the inputs and outputs of this hardware block. In this case these have been automatically added using the New Source Wizard. The architecture section still of necessity to be written for this module. 2. supervene upon the architecture block in Figure 5. 7 with the legislation in Figure 5. 18(a) and (b). This jurisprudence is a shortened down version of the initial architectural plan for the Spartan-3E FPGA appetiser Kit Board (the genuine design shipped with the board), downloaded from 7. For reference the issue code for top_level. vhd is listed in addendum A. Note that where VDHL code is listed in this tutorial, the same wring secret writing as Project Navigator is used, to do with readability. 3. provided the file by selecting File and from the main menu.
