HDFIT.SystolicArray

This repository is part of the Hardware Design Fault Injection Toolkit (HDFIT). HDFIT enables end-to-end fault injection experiments and comprises additionally HDFIT.NetlistFaultInjector and HDFIT.ScriptsHPC.

This repository provides a System Verilog systolic array implementation with a test bench, plus the interface "systolicArraySim.a" between the cycle-based simulation of the former and high-level matrix multiplication invocations in OpenBLAS. To this end, this repository also contains an 'openblas' make target, which clones OpenBLAS, applies a git-patch to implement the fault injection interface and compiles the OpenBLAS library (see openblas folder).

Dependencies

When using Ubuntu, please install these dependencies by hand as Ubuntu versions are more than two years old.

• sv2v (no need to install, compiling is sufficient). Tested with v0.0.10-1-gc00f508.
• Yosys. Tested with v0.20+22.
• Verilator. Clone from Github. Tested with v4.225.
• HDFIT.NetlistFaultInjector

Compiling

• In the Makefile, set VERILATOR_TOP and NETLIST_FAULT_INJECTOR_TOP on top of the file to the correct locations (and compile netlistFaultInjector!).
• In sv2v.sh and sv2v_fma.sh, it is assumed that the sv2v command can be found via PATH.
• 'make testNetlist && ./testNetlist' to run unit tests.
• 'make systolicArraySim.a' to generate the library used as HDFIT RTL fault simulation interface.
