(directory)Details
- arange_arrays¶
List of all arrays to be filled with numbers (list of (var, varname, start) tuples
- array_cache¶
Dictionary mapping
ArrayVariable
objects to their value or toNone
if the value (potentially) depends on executed code. This mechanism allows to access state variables in standalone mode if their value is known at run time
- arrays¶
Dictionary mapping
ArrayVariable
objects to their globally unique name
- build_on_run¶
Whether a run should trigger a build
- build_options¶
build options
- code_lines¶
Code lines that have been manually added with
device.insert_code()
Dictionary mapping slot names to lists of lines. Note that the main slot is handled separately as part ofmain_queue
- dynamic_arrays¶
List of all dynamic arrays Dictionary mapping
DynamicArrayVariable
objects with 1 dimension to their globally unique name
- dynamic_arrays_2d¶
Dictionary mapping
DynamicArrayVariable
objects with 2 dimensions to their globally unique name
- enable_profiling¶
Whether to generate profiling information (stored in an instance variable to be accessible during CodeObject generation)
- has_been_run¶
Whether the simulation has been run
- profiled_codeobjects¶
CodeObjects that use profiling (users can potentially enable profiling only for a subset of runs)
- project_dir¶
The directory which contains the generated code and results
- static_arrays¶
Dict of all static saved arrays
- synapses¶
Set of all existing synapses
- timers¶
Dictionary storing compile and binary execution times
- zero_arrays¶
List of all arrays to be filled with zeros (list of (var, varname) )
- build(directory='output', compile=True, run=True, debug=False, clean=False, with_output=True, additional_source_files=None, run_args=None, direct_call=True, **kwds)[source]¶
Build the project
TODO: more details
- code_object(owner, name, abstract_code, variables, template_name, variable_indices, codeobj_class=None, template_kwds=None, override_conditional_write=None, compiler_kwds=None)[source]¶
- code_object_class(codeobj_class=None, fallback_pref=None)[source]¶
Return
CodeObject
class (eitherCPPStandaloneCodeObject
class or input)
- delete(code=True, data=True, directory=True, force=False)[source]¶
Delete code and/or data generated/stored by the device.
- network_run(net, duration, report=None, report_period=10. * second, namespace=None, profile=None, level=0, **kwds)[source]¶
- reinit()[source]¶
Reinitialize the device. For standalone devices, clears all the internal state of the device.
