title: Virtual Prototyping through Modular Full-System Simulation
subtitle: |
Streamlining heterogenous system design, implementation, and eval,
reducing cost and increasing velocity,
through modular full system simulation.
no_page_title: true
permalink: /technology.html
card_text: |
SimBricks is an open-source, modular simulation framework enabling full
end-to-end evaluation of modern heterogeneous systems by combining
battle-tested simulators for different system components like machines (e.g.
QEMU, gem5, Simics), hardware components (e.g. Verilator, Tofino, FEMU SSD),
and networks (e.g. ns-3, OMNeT++). SimBricks is fast, scalable, accurate and
deterministically connects and synchronizes simulators while being able to run
unmodified full system stacks, including applications, operating systems such
as Linux, and hardware RTL.

## SimBricks: Full-System Simulation for Heterogeneous Systems
SimBricks is an open-source simulation framework that enables full end-to-end
evaluation of modern heterogeneous systems in simulation. Our primary aim is to
enable rapid prototyping and meaningful performance evaluation. SimBricks
modularly combines and connects battle-tested simulators for different
components: machines (e.g. QEMU, gem5, Simics), hardware components (e.g.
Verilator, Tofino, FEMU SSD), and networks (e.g. ns-3, OMNeT++). SimBricks
simulations run unmodified full system stacks, including applications, operating
systems such as Linux, and hardware RTL.

## Late Full-System Evaluation Slows Development and Increases Risk
Heterogeneous hardware-software systems are complex, slow, and expensive to
build, in academia and industry alike. These systems aim to drastically improve
performance and energy efficiency of the *complete* system or application.
However, engineers can only measure overall system performance once all software
and hardware components have been implemented and manufactured. As a result, key
metrics for evaluating design and implementation are only available late in the
project lifecycle, once a physical testbed can actually be fully built.
</div>
{::options parse_block_html="true" /}
<div class="block-50">
## Early & Continuous Full-System Results Accelerate Building Heterogeneous Systems
Enabling developers to run and measure the full system early speeds up and
reduces risks for building heterogeneous systems. Developers can choose optimal
design parameters before implementation based on reliable metrics. Full-system
integration tests reduce the need for extensive hardware testbenches that merely
emulate the real behavior. And once the hardware implementation is complete, a
reliable full-system performance evaluation before manufacturing provides early
feedback to developers, reviewers, and customers.
</div>
{::options parse_block_html="true" /}
<div class="block-50">
## Modular Simulation Enables Early and Continuous Evaluation
Simulation generally enables early evaluation when a physical implementation is
out of reach. However, typical heterogeneous systems require a broad range of
components not supported by any individual simulator. To address this, we take a
modular approach of combining different best-of-breed simulators for the
individual components. We flexibly connect and synchronize multiple parallel
instances of these simulators into a broad range of complete, *end-to-end*
virtual testbeds.

NIC simulated through Verilator. The two clients are simulated in QEMU
and connect to a PCIe behavioral NIC model. All three hosts are
connected through a network simulated in ns-3.">
