set_directive_disaggregate

Description

The set_directive_disaggregate command lets you deconstruct a struct variable into its individual elements. The number and type of elements created are determined by the contents of the struct itself.

IMPORTANT: Structs used as arguments to the top-level function are aggregated by default, but can be disaggregated with this directive or pragma. Refer to AXI4-Stream Interfaces for important information about disaggregating structs associated with streams.

  • <location> is the location (in the format function[/label]) where the variable to disaggregate is found.
  • <variable> specifies the struct variable name.

Options

This command has no options.

Examples
