A default config can be found in the `obi_pkg.sv`. This config should be aligned with the `req` and `rsp` structs.\n- `obi_req_t`: The OBI request struct is designed to be generated with a macro available in the `include/obi/typedef.svh` include file and has fields for the handshake and a field for the *A* channel.\n- `obi_rsp_t`: The OBI response struct is designed to be generated with a macro available in the `include/obi/typedef.svh` include file and has fields for the handshake and a filed for the *R* channel.\n\nMost IPs will also support a SystemVerilog `interface` variant, also based on `ObiCfg`.\n\n## Available IPs\n- `obi_mux.sv`: A multiplexer IP for the OBI protocol.\n- `obi_demux.sv`: A demultiplexer IP for the OBI protocol.\n- `obi_xbar.sv`: A crossbar interconnect IP for the OBI protocol.\n- `obi_err_sbr.sv`: A error subordinate, responding with the error bit set.\n- `obi_sram_shim.sv`: An adapter for a standard sram.\n- `obi_atop_resolver.sv`: An atomics filter, resolving atomic operations on an exclusive bus.\n- `apb_to_obi.sv`: A protocol converter from APB to OBI.\n- `obi_to_apb.sv`: A protocol converter from OBI to APB.\n\n## License\nSolderpad Hardware License, Version 0.51\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulp-platform%2Fobi","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpulp-platform%2Fobi","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulp-platform%2Fobi/lists"}
