E6863 Project - Fridge Model Checking

This is the final project for Columbia University CSEE E6863 Formal Verification HW/SW System. It aims at performing bounded model checking on Fridge, a multi-threaded key-value store that supports nonblocking and blocking GET operation, to help locating bugs that are hard to find via normal testing method.

This project utilizes CBMC to perform model checking.

Get Started

As CBMC requires adding code that cannot be normally compiled, the master branch of the repository is for running CBMC.

To run unit tests and e2e tests, you need to switch to the test tag using:

git checkout test

Run Fridge

To run fridge, use the following make command to compile:

make app

and run the executable:

./app

Run the unit tests

All the unit tests are located in test/unit_test.c.

To run the unit tests, use the following make command to compile:

make unit_test

and run the executable:

./unit_test

Run the end-to-end tests

All the end-to-end tests are located in test/e2e_test.c.

To run the unit tests, use the following make command to compile:

make e2e_test

and run the executable:

./e2e_test

Run CBMC Model Checking

Function-Level

We implemented function-level model checking for kkv_init, kkv_destroy, kkv_get and kkv_put.

To run CBMC on each function, you need to comment out the other three functions and then run the corresponding command in the Makefile.
