ASIC-in-the-loop methodology for verification of piecewise affine controllers

Abstract

This paper exposes a hardware-in-the-loop metho- dology to verify the performance of a programmable and confi- gurable application specific integrated circuit (ASIC) that imple- ments piecewise affine (PWA) controllers. The ASIC inserted into a printed circuit board (PCB) is connected to a logic analyzer that generates the input patterns to the ASIC (in particular, the values to program the memories, configuration parameters, and values of the input signals). The output provided by the ASIC is also taken by the logic analyzer. A Matlab program controls the logic analyzer to verify the PWA controller implemented by the ASIC in open-loop as well as in closed-loop configurations.
