A filter - Supplementary materials

This repository contains accompanying material and code needed for reproducing results in the paper:R. Pilipović, V. Risojević, P. Bulić *"On the Design of an Energy Efficient Digital IIR A-weighting Filter using Approximate Multiplication"*For Verilog to GDS synthesis flow, we employed OpenROAD Flow, representing a full RTL-to-GDS flow built entirely on open-source tools. Besides OpenROAD, we used the Vivado suite from Xilinx to deploy the proposed filter on the ZYBO Z7 board. The supplementary material is organized as follows:
