Distributed Control in Testable High-Level Synthesis with Low Area and Power Overhead Haidar Harmanani and Wissam Marrouche Department of Computer Science Lebanese American University Byblos, 1401 2010, Lebanon Abstract— This work presents a method for distributed test test system and a test schedule, generate a distributed control in coordination with testable data path allocation in test controller that meets the following constraints: high-level synthesis. The method aims at creating distributed test 1) exercise the behavior during normal mode and test controllers for synthesized data paths with the aim of minimizing area and power consumption. The distributed controllers are the circuit during test mode; 2) minimize the power designed to be small and mounted next to their corresponding consumption during normal and test execution. test kernels. Thus, every test kernel in the datapath has its own The above problem is solved using a hierarchical controller test controller in addition to a relatively small controller that approach where every test kernel in the datapath has its synchronizes the distributed controllers. The system has been implemented using C++ and favorable results are reported. own test controller in addition to a relatively small controller that synchronizes the distributed controllers. This work is I. INTRODUCTION motivated by the following: The design and test of electronic circuits can be tackl
