TreeCore Sim: A Lightweight cloudFPGA Prototype for Processor Simulation

Overview

Motivation

Feature

Usage

NOTE:

Install

$ git clone https://github.com/microdynamics-cpu/tree-core-sim.git
$ cd tree-core-sim
$ mkdir dependency && cd dependency

Then, adding extra swap sapce to avoid the exhaustion of heap memory.

NOTE: Below steps is not essential. If your embedded platform have more that 4GB memory space, you can just skip these steps.

$ mkdir -p ~/Desktop/swap
$ cd ~/Desktop/swap
$ sudo swapoff -a
$ sudo dd if=/dev/zero of=swapfile bs=1024 count=4000000 # 4GB swap file size
$ sudo mkswap swapfile
$ sudo swapon swapfile

NOTE: The installation sequence of libraries is not arbitrary, some libraries have dependency relation. So you should install libraries one by one in order that's been exhibited here.

$ sudo apt-get install build-essential clang bison flex libreadline-dev gawk tcl-dev libffi-dev git mercurial graphviz xdot pkg-config python python3 libftdi-dev qt5-default python3-dev libboost-all-dev cmake libeigen3-dev
$ git clone https://github.com/YosysHQ/icestorm.git icestorm
$ cd icestorm
$ make -j$(nproc)
$ sudo make install

If your embedded platform is short of memory, you can decrease the number of jobs by switch -j$(nproc) into -j1.

$ git clone https://github.com/cseed/arachne-pnr.git arachne-pnr
$ cd arachne-pnr
$ make -j$(nproc)
$ sudo make install
$ git clone https://github.com/YosysHQ/nextpnr nextpnr
$ cd nextpnr
$ cmake -DARCH=ice40 -DCMAKE_INSTALL_PREFIX=/usr/local .
$ make -j$(nproc)
$ sudo make install

NOTE: After nextpnr compiled done, if you encouter error in link phase like error: lto-wrapper failed collect2: error: ld returned 1 exit status, that possible means the compiler of your embedded platform cannot support the IPO perfactly. You need to switch USE_IPO option from ON to OFF in CMakefile.txt.

$ git clone https://github.com/YosysHQ/yosys.git yosys
$ cd yosys
$ make -j$(nproc)
$ sudo make install
