JSON.sv is a SystemVerilog package that enables you to read, manipulate, and write JSON object trees.

JSON.sv uses the FuseSoC package manager to abstract from any HDL simulator you might want to use.

After cloning the repository or downloading the JSON.core file you need to add it to a local FuseSoC library:

fusesoc library add <name> JSON.core

If you have decided to only donwload the JSON.core file you need to uncomment the lines that describe the file provider.

fusesoc run FPGA_Garage:util:JSON

fusesoc run --build FPGA_Garage:util:JSON
make -C build/FPGA_Garage_util_JSON_0/sim-<your simulator> run-gui

The test program in sv/json_test.sv contains example calls for all the available API.
