Recursos de Laboratório

Para uso fora do IFSC dos recursos computacionais com licença educacional, o IFSC disponibiliza para seus alunos o IFSC-CLOUD. Atualmente a forma mais eficiente de acesso é através do Cliente X2GO. O procedimento de instalação/ configuração e uso do Quartus/Modelsim/QSIM está descrito em Acesso ao IFSC-CLOUD#Cliente X2GO (recomendado).

Para a geração de documentação/relatórios técnicos/artigos, está disponibilizada a plataforma Sharelatex do IFSC-CLOUD. Utilize preferencialmente o modelo de artigo no padrão ABNT.

Homework 1

Combinational Circuits (Prazo de entrega 19/02/2015)

Download the Operator Sharing Source Code (qar) or Operator Sharing Source Code (qar.zip) and, for each architecture of each one of the three examples, do the following:

  • Choose one of the available FPGA families for your project (e.g. Cyclone IV GX);
  • Select the "Fastest" "Speed grade";
  • Select the smallest device available in the family;
  • For each architecture of the example, compile the it, analyze the RTL output, and take note of the number of logic elements/LUTs consumed, and of the highest delay in the circuit;
  • Change to the largest device available in the family;
  • For each architecture of the example, compile the it, analyze the RTL output, and take note of the number of logic elements/LUTs consumed, and of the highest delay in the circuit;

Write a report containing the numeric results of your experiments. For each example, answer the following questions:

  1. Was there any differences between the RTL generated for each architecture? Why did this happen (or not)?
  2. Was there any differences between the RTL generated, for the same architecture, for different devices? Why did this happen (or not)?

Email the results to the professors until 17/02/2015.
