1 CHAPTER 1 PROBLEMS 1.1 Please draw out the complete schematic diagram using only primitive circuit elements (no blocks) that is represented by the hierarchical decomposition shown in Fig. P1.1. 1.2 In this problem we will start with a complete device-level cir- cuit diagram as shown in Fig. P1.2. In addition, we are told that the natural cell-level blocks which can be used to compose a more abstract higher-level representation are shown at the bottom of Fig. P1.2. Please draw TWO different possible ways in which you could draw a circuit diagram containing only the modules TWO_R and THREE_R both of which would repre- sent the given complete circuit diagram.

Unformatted text preview: of the module “FOO” is used to implement the system. In order to be able to refer to the two instances uniquely, we assign them different instance numbers. However, every instance of a given module is identical and is described by the definition of “FOO” given at the bottom.
