6.7.8. Wire-Level Connection Commands

Wire-level commands accept optional input ports and wire-level expressions as arguments for the qsys-script utility and in _hw.tcl files.

You can use wire-level commands to:

  • Apply a wire-level expression to a port with set_wirelevel_expression.
  • Retrieve a list of expressions from a port, instance, or all expressions in the current level of system hierarchy with get_wirelevel_expression.
  • Remove a list of expressions from a port, instance, or all expressions in the current level of system hierarchy with remove_wirelevel_expression.
Note:

The following restrictions apply when using wire-level commands _hw.tcl files:

  • Wire-level commands are only valid in a composition callback.
  • Wire-level expressions can only be applied to instances created by add_instance.
