Usage

Setup Regfile and Regfile Device for Access

See tests/fixtures.py how to create a regfile by deriving from the Regfile class. Implement read/write functions and pass them (or overwrite while deriving) to an adequate RegfileDevice class.

Accessing Registers

    # dict like:
    regfile["reg1_high"] = {"cfg": 0x0AA, "cfg_trigger": 0x0, "cfg_trigger_mode": 0x0}
    # or single field (might issue read-modify-write)
    regfile["reg1_high"]["cfg"] = 0xB

    # uvm like:
    regfile.reg2_r.config_f.set(2)
    regfile.reg2_r.update()

    # write_update
    regfile["reg_addr40_r"].write_update(start=1, enable_feature0=0, enable_feature1=0)

    # read (can be int or dict or string context)
    assert entry["cfg"] == 0x22
    print(entry["cfg"])

    # read entire entry to an variable, so that no further read request will be issued
