Implementation of Systolic Array for the Single-Source Shortest Path Problem

Shortest path problem belongs to the combinatorial optimization problem and plays an important role in the field of computer aided design. It can either be directly applied as in the case of routing or serves as a important subroutine in more complex problems. In this paper, a systolic array for the SSSP(single-source shortest path problem) was derived. The array was modeled and simulated in RTL level using VHDL, then synthesized to a schematic and finally implemented to a layout using the cell library based on 0.35 $\mu\textrm{m}$ CMOS 1-poly 4-metal CMOS technology.
