+# Simulation Environment Setup
+
+There are two options for setting up the simulation environment:
+
+* Pulling a pre-built docker image
+* Installing the dependecies locally
+
+## 1. Docker
+
+There is an available docker setup with the needed tools at [efabless/dockerized-verification-setup](https://github.com/efabless/dockerized-verification-setup)
+
+Run the following to pull the image:
+
+```
+docker pull efabless/dv_setup:latest
+```
+
+## 2. Local Installion (Linux)
+
+You will need to fullfil these dependecies:
+
+* Icarus Verilog (10.2+)
+* RV32I Toolchain
+
+Using apt, you can install Icarus Verilog:
+
+```bash
+sudo apt-get install iverilog
+```
+
+Next, you will need to build the RV32I toolchain. Firstly, export the installation path for the RV32I toolchain,
+
+```bash
+export GCC_PATH=<gcc-installation-path>
+```
+
+Then, run the following:
+
+```bash
+# packages needed:
+sudo apt-get install autoconf automake autotools-dev curl libmpc-dev \
+ libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo \
+ gperf libtool patchutils bc zlib1g-dev git libexpat1-dev
+
+sudo mkdir $GCC_PATH
+sudo chown $USER $GCC_PATH
+
+git clone https://github.com/riscv/riscv-gnu-toolchain riscv-gnu-toolchain-rv32i
+cd riscv-gnu-toolchain-rv32i
+git checkout 411d134
+git submodule update --init --recursive
+
+mkdir build; cd build
+../configure --with-arch=rv32i --prefix=$GCC_PATH
+make -j$(nproc)
+```
+
+# Running Simulation
+
+## Docker
+
+First, you will need to export a number of environment variables:
+
+```bash
+export PDK_PATH=<pdk-location/sky130A>
+export CARAVEL_ROOT=<caravel_root>
+export UPRJ_ROOT=<user_project_root>
+```
+
+Then, run the following command to start the docker container :
+
+```

+## Both
+
+To run RTL simulation for one of the DV tests,
+
+```bash
