The code present in this repository is a research project done for ECE 527 System-on-chip design. It explores methods for using clock gating with Xilinx 7-series FPGAs using the NoC.
Most files in this repository are part of OpenSoC Fabric. The following scala files were modified by us: src/main/scala/main.scala src/main/scala/router.scala src/main/scala/routerTester.scala src/main/scala/topology.scala
The file below contains our original code src/main/scala/mymesh.scala manual_edit/VCRouterBypass.v manual_edit/My_MeshWrapper-harness.v
The remaining file in manual_edit is a slightly modified form of the generated NoC.
- Extract the Vivado project
vivado_files/noc.xpr.zip - Edit the testbench
My_MeshWrapper-harness.vto enable or disableio_bypass_1 - Run behavioral simulation.
a. Use the following commands to get an saif:
restart
open_saif "A.saif"
log_saif [get_objects -r *]
run 30 us
close_saif
b. Run synthesis and input the saif file to power analysis.
Recent advancements in technology scaling have shown a trend towards greater integration with large-scale chips containing thousands of processors connected to memories and other I/O devices using non-trivial network topologies. Software simulation proves insufficient to study the tradeoffs in such complex systems due to slow execution time, whereas hardware RTL development is too time-consuming. We present OpenSoC Fabric, an on-chip network generation infrastructure which aims to provide a parameterizable and powerful on-chip network generator for evaluating future high performance computing architectures based on SoC technology. OpenSoC Fabric leverages a new hardware DSL, Chisel, which contains powerful abstractions provided by its base language, Scala, and generates both software (C++) and hardware (Verilog) models from a single code base. The OpenSoC Fabric infrastructure is modeled after existing state-of-the-art simulators, offers large and powerful collections of configuration options, and follows object-oriented design and functional programming to make functionality extension as easy as possible.
