A logic circuit consists of combinational logic and sequential logic circuit elements. The combinational logic is defined by a Boolean logic expression (refer to Chapter 5 for an introduction to digital logic t
4.1 Introduction Logic circuit Combinational circuit Sequential circuit Combinational circuits consist of logic gates Sequential circuits consist of storage elements and logic gates 4.2 Combinational Circuits A Combinational Circuit consists of logic gates its outputs are determined from the present inputs 4.3...
System and software for verifying that a model of an integrated circuit satisfies its specification includes performing a sequence of at least one sequential transformation on a sequential model of the integrated circuit to produce a simplified sequential model of the integrated circuit. Thereafter, the...
high-performance Building Block IP. The DesignWare Library Datapath and Building Block IP are tightly integrated into Design Compiler (DC) and are part of the DC installation. The Library has a number of arithmetic, combinational, sequential, and floating point components, and many other blocks su...
As will be described in Chapters 5 and 6, memory is a characteristic of sequential, but not combinational, circuits. 10The mask, requiring minute attention, is expensive to produce. Hence, mask-programmable ROMs are used only when the cost is justified by very large production runs. 154 ...

between combinational logic and sequential logic is that, in sequential logic the output depends not only on the present input but also on the history of the input but in combinational logic, the output is a pure function of the present input only.The combinational logic circuit has no memory...
Attempts have been made to solve the problem of combinational loops. In one approach, combinational loop analysis uses binary decision diagrams (BDDs) to detect whether a sequential circuit with combinational loops exhibits standard synchronous behavior. If so, an equivalent circuit without combinational...
