hwtSimApi.basic_hdl_simulator.model_utils.sensitivity(proc_fn, *sensitiveTo: List[BasicRtlSimProxy | Tuple[Tuple[bool, bool], BasicRtlSimProxy]])

register sensitivity for process

hwtSimApi.basic_hdl_simulator.proxy module

class hwtSimApi.basic_hdl_simulator.proxy.BasicRtlSimProxy(sim: BasicRtlSimulator, parent, name, dtype, def_val)

Bases: object

Signal proxy which manages the access to a memory in simulation

Variables:

  • ~.callbacks – list of sim processes which will be waken up if signal value is updated

  • ~.sim – main simulator

  • ~._name – name of property which is this proxy stored in on parent

  • ~._hdlName – signal name which was used in HDL

  • ~._dtype – data type of this signal

  • ~._origin – the object which was this proxy generated from

  • ~._ag – agent which controls this proxy

  • ~.parent – parent object

  • ~.def_val – value used for initialization of value (done on sim. startup)

  • ~.val – actual value of signal

  • ~.val_next – place for metainformations about next update
