Getting Started

Prerequisites for Building tlpcc

• CMake 3.13+
• A C++11 compiler

Prerequisites for Using tlpc

• tlpcc
• Google glog library
• Clang headers
• Python 3 and its requirements
  • pyverilog
  • haoda

How to install CMake 3.13+ on Ubuntu 16.04+ and CentOS 7?

Ubuntu 16.04+

sudo apt install python-pip
sudo -H python -m pip install cmake

CentOS 7

sudo yum install python-pip
sudo python -m pip install cmake

How to install Google glog library on Ubuntu and CentOS?

Ubuntu

sudo apt install libgoogle-glog-dev

CentOS

sudo yum install glog-devel

How to install the latest Clang on Ubuntu?

Follow the instructions here. Note that running tlpcc doesn't require the latest Clang; old (e.g. Clang 3.8) headers are fine.

How to install Python pyverilog on Ubuntu?

sudo apt install iverilog python3-pip
sudo python3 -m pip install pyverilog

How to install Python haoda?

sudo apt install python3-pip
sudo python3 -m pip install haoda

Run tests

mkdir build
cd build
cmake ..
make
make test

Known Issues

• Template functions cannot be tasks
• Tasks cannot invoke functions with tlp::stream or tlp::mmap
• Loops generated by convenient EoS macros must be manually pipelined
