Abstract
In this paper, we consider the problem of minimizing the number of logic modules for Actel 2 or Actel 3 sequential circuits. We make use of the fact that if a flip-flop is the only destination of its driving combinational block, then both the flip-flop and the combinational block can be put in a sequential module. Retiming technique is applied to minimize the number of registers that can not be merged with combinational blocks. We formulate the problem as an integer linear program. We show that the constraint matrix of the integer program is totally unimodular. As a result, we can solve our logic module minimization problem optimally by solving the linear relaxation of the integer program.
