Modules for which the attribute NoRuntime is set do not use any functionality controlled by the parameters in their common$ structures. For such modules, these parameters are set to the following values, and cannot be changed, to guarantee that NoRuntime modules do not accidentally request functionality they don not use.

All modules have this configuration parameter. Its name contains the '$' character to ensure it does not conflict with configuration parameters declared by the module. This allows new configuration parameters to be added in the future without any chance of breaking existing modules.

This structure defines the default values for the configuration parameters shared by all modules in a system. Unless otherwise noted, setting one of the fields defined below will set the corresponding value for all modules in the system which have not been explicitly set; i.e., it will establish a default value for the parameter.

However, the modules from this package (xdc.runtime) are an exception. The values from Default.common$ are not copied to logger and diags_ properties of common$ in xdc.runtime modules. The property diags_ASSERT is an exception to that exception. Its value from 'Default.common$ is copied to all modules for which diags_ASSERT` has not been explicitly set.

Enables asserts at runtime. Default is ALWAYS_ON

Enables entry trace for all functions. Default is ALWAYS_OFF

Enables exit trace for all functions. Default is ALWAYS_OFF

Enables internal asserts. Default is ALWAYS_OFF. When set to ALWAYS_ON, requires diags_ASSERT to be ALWAYS_ON.

Enables logging of lifecycle events. These events are logged during creates and deletes. Default is ALWAYS_OFF.

Enables logging of status events, such as error and warning events. Default is ALWAYS_ON. Note that this does not mean that logging will occur by default--a logger instance must also be configured for the module in order for events to be logged.

Enables logging of generic informational events. Default is ALWAYS_OFF.

Enables logging of analysis events, such as benchmarking events. Default is ALWAYS_OFF.

Each diags_USER field controls a separate user-defined logging level. Default is ALWAYS_OFF for all diags_USER fileds.

Default gate used by all modules which are declared as being @Gated. By default, this parameter points to an instance of GateNull, which means there is no protection.

The default parameters used to create gates at runtime. See Types.Common$.gateParams. Default is null.

Specify heap to be used for module instances. Default is null. If instanceHeap is null, instances will be allocated from the heap specified by Memory.defaultHeapInstance.

Specify section to be used to place module instances. Default is null.

Default logger used by modules to write logs. By default there is no logger.

Used to specify type of application. Types.STATIC_POLICY is used when all objects are created statically. Types.CREATE_POLICY is used when the application creates objects at runtime. Types.DELETE_POLICY is used when the application creates and deletes objects at runtime. This helps eliminate unwanted create and delete code.

This parameter should be set to true if space needs to be allocated in instance objects for instance names. Allocating space for a name allows object view tools to display the names. The runtime functions Mod_Handle_name() and Mod_Handle_label() defined for each module Mod can be used to retrieve the name at runtime.

This field allows the name of the module to be retained on the target. Setting this to false will save space but will also prevent the target from being able to display the module names appearing in Log events and Errors.

Setting namedModule to false causes all modules, except for Memory and Main to be unnamed by default. To eliminate the string names for these modules you must explicitly set their common$.namedModule parameters to false; without these two names, target-side display of error messages is somewhat cryptic.

Specify whether modules that are allocated to ROM are patchable.

Get the value of a member of the structure common$ based on defaults and the current value of the parameter. If the current value of param is undefined, the function returns the default value for that parameter from Default.common$.

Returns the value of the parameter named param from the module mod.
