Getting Started

Prerequisites

LLC can directly be integrated after cloning it from this repository. However, to build the documentation, and run various checks on the source code, various tools are required.

• bender >= v0.26.1
• morty >= v0.8.0
• Verible >= v0.0-1051-gd4cd328
• Python3 >= 3.8 including some the libraries listed in requirements.txt

Building the Documentation

Use make doc to build the documentation. The output is located at doc/morty.

Simulation

We currently do not include any free and open-source simulation setup. However, if you have access to Questa advanced simulator, a simulation can be launched using:

sh> make scripts/compile_vsim.tcl
sh> questa-2021.3 vsim -64
vsim> source scripts/compile_vsim.tcl
vsim> source scripts/start_vsim.tcl
vsim> do scripts/waves/tb_axi_llc.vsim.do
vsim> run -all

The simulation should complete after 53.168ms.
