predict-T

This project is an extension of the The Gem5 Simulator for studying the interactions between microprocessor and power supply and power delivery network. This novel framework combines two academic state of the art simulators with a realisic Verilog AMS model of the power supply, motherboard, and on chip power delivery networks.

Structure

The repository contains the following directories:

• circuit_model - Verilog AMS code and Scripts to run the Cadence VerilogAMS circuit simulation.
• git_util - Git hooks and other scripts for managing the repository
• python - Python utilities
  • mcpat_autogen - Python code for converting the Gem5 stats to McPAT XML
  • analysis - Python utilities for plotting and generating test data
• runscript - Folder containing setup scripts and run scripts

Dependencies

Cadence Aug2016

This project is dependent on Cadence AUG2016 and requires a license to enable the circuit level simulation (NCVerilog/Spectre). Other open source tools at the moment are not supported however there are plans to eventually replace this requirement with a free tool.

The Cadence tools can be obtained locally with the following commands:

First sign in to UIUC EWS and load the Cadence AUG2016 module:

module load cadence/Aug2016

Second transfer the cadence tools to the local machine with rsync:

rsync -rvlR /software/cadence-Aug2016 <user>@<remote.machine.url>:/home/<user>/cadence

Depending on network speed this may take a couple of hours and will use approximately 70GB of drive space.

Architecture Simulators

The project also requires building forked Gem5 and McPAT repositories:

• McPAT Fork
• GEM5 Fork

Build & Run

To build and run the project set the paths in setup.sh

To build the docker container required by Cadence AUG2016, and set the environment variables:

source runscript/setup.sh

Adjust the paths in run.sh to point to the test executables and the input files, and run the the tests:

runscript/run.sh

Versioning and Features

Version 0.0.0 - Currently not released as an official tool. Needs open source circuit sim tool support first.

Future Work

Please see the open issues for the improvements to the project.
