AN-1062 GreenPAK Macro Cell Design Constructing additional DFF types
D-type flip flops are used in many GreenPAK designs. Sometimes a user may need more of them than the available pre-configured DFF blocks in the GreenPAK IC. Reference books can give a variety of solutions on how to construct DFF’s. However, some are not efficient designs. The following is a collection of solutions with working examples using GreenPAK. Emphasis is on simplicity, and minimizing circuit resource usage.
