Quick Launch for Designers

Dependencies

Docker: Linux || Windows || Mac with Intel Chip || Mac with Apple Chip

Running the simulation

Assuming you already:

went throught the quick start for setting up your environemnt,
integrated your design into the user's wrapper and
hardenned your design as well as the user's wrapper (for GL simulation)

make simenv
SIM=RTL make verify-<dv-test>
# OR
SIM=GL make verify-<dv-test>

<dv-test>: io_ports, mprj_stimulus, la_test1, la_test2 or wb_port.

For advanced users

Simulation Environment Setup

There are two options for setting up the simulation environment:

Pulling a pre-built docker image
Installing the dependecies locally. Instructions to setting up the environment locally can be found here

Docker

There is an available docker setup with the needed tools at efabless/dockerized-verification-setup

Run the following to pull the image:

docker pull efabless/dv_setup:latest

Running Simulation

First, you will need to export a number of environment variables:

export PDK_PATH=<pdk-location/sky130A>
export CARAVEL_ROOT=<caravel_root>
export TARGET_PATH=<caravel_user_project>

Then, run the following command to start the docker container :

docker run -it -v ${TARGET_PATH}:${TARGET_PATH} -v ${PDK_ROOT}:${PDK_ROOT} \
		-v ${CARAVEL_ROOT}:${CARAVEL_ROOT} \
		-e TARGET_PATH=${TARGET_PATH} -e PDK_ROOT=${PDK_ROOT} \
		-e CARAVEL_ROOT=${CARAVEL_ROOT} \
		-e TOOLS=/foss/tools/riscv-gnu-toolchain-rv32i/411d134 \
		-e DESIGNS=$(TARGET_PATH) \
		-e CORE_VERILOG_PATH=$(TARGET_PATH)/mgmt_core_wrapper/verilog \
		-e MCW_ROOT=$(MCW_ROOT) \
		efabless/dv_setup:latest

Then, navigate to the directory where the DV tests reside :

cd $TARGET_PATH/verilog/dv/

To run any simulation, you need to be on the top level or caravel_user_project.

To run RTL simulation for one of the DV tests,

SIM=RTL make verify-<dv-test>

To run gate level simulation for one of the DV tests,

SIM=GL make verify-<dv-test>
