Floorplanned Spectrometer

Status: Mature

Introduction

In this project, wideband, high resolution spectrometers designed in the MLW are presented. Increase in frequency channels and bandwidth are achieved with a technique called Floorplannig, which consists in helping the Place-and-Route (PAR) algorithms by manually placing and/or constraining the position of specific FPGA resources in the chip.
