Constructor Details

#initialize(name = :"", systemT = nil, &ruby_block) ⇒ Scope

Creates a new scope with possible +name+. If the scope is a top scope of a system, this systemT is given by +systemT+.

The proc +ruby_block+ is executed for building the scope. If no block is provided, the scope is the top of a system and is filled by the instantiation procedure of the system.

Converts the scope to HDLRuby::Low. +name+ is the name of the system containing the new low scope in case of top scope, should be used as name for it. NOTE: by convention, the name of the top scope is the name of the system.
